Packaging Second Nuc for Transport

Sunday 27th June
This is the second colony we are rehoming with another local beekeeper. It was originally supposed to be collected at the same time as the first nuc but it has now had an extended varroa treatment (using brood removal and bait frames). This has set the development of this colony back considerably but it's now in full health so should easily build up their numbers rapidly over the next few weeks.
I came out at 10:30pm and there were still quite a large number of bees crowding in the entrance and over the front of the nuc. They need to be sealed inside tonight so that it is safe to relocate the whole colony tomorrow morning but I didn't want to squash any with my bung! I decided to come out later at night and try again...

As I walked back to the house I heard a real noise coming from this colony, Dipsy's. I could hear a definite humming noise from both of the other hives but this one was almost roaring!
Peeping inside the entrance explained the noise - the whole left hand side was crammed full of fanning bees! They were all sitting there forcing a cool draught up through the hive. Hopefully this is a good sign of there being a large amount of nectar stored in there to evaporate (nectar is about 80% water but stored honey is less than 20% water).
I came out again just after midnight armed with my handy water mister - there were just two in the front entrance and a quick squirt of the water spray made them disappear inside. Before they realised it was just a trick, not a shower of rain, I bunged up the entrance with a wedge of hessian.
I used a short ratchet-strap in one direction (also holding the entrance bung securely in place), then an elastic bungy cord in the other direction - not nearly as fragile-looking as those lengths of packing tape I used last time!
It was pitch dark by this time of night but I didn't want to leave the nuc standing here until morning - the early morning sun on it could be fatal for all those bees shut up inside with so little ventilation. This meant feeling my way along the darkness carrying the nuc back to the barn, with a torch secured under the strap on top pointing the way!
I made it all the way back with everything still secure and found a good shady spot to leave it until the morning.
It was collected at 11am and they should be out in their new home by lunchtime.

The Last Queen Hatches

Saturday 26th June
Just a few quick jobs to take care of today. Both these two nucs need to be checked - N1 needs a varroa bait frame removed and the colony in N2 is due to be rehomed this weekend, assuming that there are no health concerns inside.
N1 first. I have briefly opened this nuc a couple of times already this week - the bait frame has still had sealed worker brood (hopefully trapping every varroa mite in the colony inside it) as well as two sealed queen cells. I need to destroy this frame to eradicate the varroa but the queen seems to be taking much longer to hatch than I expected.
However, finally here she is - a newly-hatched virgin queen and practically all the worker brood is still sealed too.
She seems much slimmer and longer than our previous newly-hatched queens we have seen this year. These bees are all mongrels, not bred from pure stock, so it is not surprising that each queen would have a totally unique (and unpredictable) appearance and temperament.
Having carefully put the queen and all the other bees from this bait frame back into the nuc, we took it away to be destroyed. It goes in the freezer for a spell - it's not easy to bring myself to destroy this quantity of healthy-looking brood but every varroa mite in the colony must be incubating here on this frame too, so it is necessary for the health of the colony.
We sealed this colony back up with an empty frame to replace this one. This queen will need a fortnight to mate and then start raising her own brood.
N2 next - we fed this colony a litre of sugar syrup a few days ago to help them build up those two empty frames from the final step of this colony's bait frame treatment. They have taken it all in from the feeder and started building up that wax foundation.
This is now looking like a very healthy colony, and definitely suitable for rehoming with another beekeeper.
'Blue 2', we called this queen, not wanting to become attached to her! This colony is due to be collected on Sunday morning so I'll come back out later this evening to seal them all in for the journey. (It's only 10 miles away, which is a good thing, seeing as we are in the middle of a small heat wave here - sealing them in for a few hours could be fatal for them in extreme heat like this.)
These are our three permanent colonies - we need to remove some more bait comb from Beatrix's and to check that Dipsy has enough room for expansion. It has been clear that Dipsy's colony is by far the strongest of the lot - the number of bees in that colony is probably about the same as in the other two combined.
Beatrix first - we inserted a shallow frame into the brood box a while ago. When this happens, the bees usually build up a whole load of drone cell comb on the bottom of it. Varroa mites usually find the scent of unsealed drone brood irresistable and will always choose to breed in drone brood if it is available.
Sure enough, the whole bottom of the frame has been built up and has a large quantity of sealed drone brood.
It was easy to slice this whole section off and replace the shallow frame in the hive. Hopefully they will build this up again and we can continually slice off large sections of drone brood regularly without having to sacrifice any of the valuable worker brood.
Dipsy next - it's clear that this is a much more defensive colony than any of the others here. Right from the first moment of opening the roof, the guard bees were just constantly battering at us.
There is still plenty of room in the super, though there are not many completely empty frames left.
There isn't much room in the brood box so it looks like this one may need supering up again soon, just because of the sheer quantity of bees in here - it must be pretty cramped at night!
A good video of Dipsy scuttling about. She is clearly marked but you can see how the queen moves 'differently' to the other bees.

Our First Ever Honey Harvest

Saturday 19th June

Our local beekeeping association (Waveney Beekeepers Group - there's a link to their website on the right -->) was hosting a demonstration of extracting honey today. Being a bit unenthusiastic about the whole honey harvesting process, I have missed this demonstration for the last two years running since I started. However, I don't think there's the slightest chance we can complete this year without going through a dreaded messy honey-extraction! I closed the shop mid-afternoon (many apologies again to the citizens of Bungay, but my bees need me!) and went along.

The demonstration showed honey being harvested in great quantity, with a leaf-blower to clear the bees from many supers at a time, a huge motor-powered honey-extraction device and a giant rapid-melting tray. This was honey being harvested on a large scale but it was clear that all this technology was only necessary because of the speed required to process all this honey.

I was surprised by how uncomplicated it could actually be - I'd been expecting to come away with a whole list of more specialist equipment to buy, but I was reliably assured that it was possible to extract honey (on a small scale) quite easily without a mechanical extractor or any special equipment at all, just what we already have in the kitchen [NB - so long as it is not to be sold]

I came home and we agreed to try to extract the honey from just two frames straight away, just to see if this is actually possible. There's plenty of honey out there on the hives now and, with Father's Day tomorrow, what better gift for the two grandads in the family than a jar of 'home-grown' honey each! (Especially as they have put in hours of babysitting while we attend the bees)
I chose to remove them from Bea's colony - this is the one with the greatest quantity of stores at the moment - I guess that there's about 30lb of surplus honey sitting here right now and there could easily be much more than that by the beginning of August, when we'll be ceasing any harvesting.
This is one of the frames I took out - there were only a handful of bees on it and when I brushed them off they soon lost interest in it. It's a gloomy, gusty day and there were hardly any bees flying - those I brushed off soon disappeared back inside.
With the lid back on the hive, and these two full frames replaced with empty ones, not one single bee hung around to bother me, so I just took them straight indoors.
We got out all the equipment ready - luckily I always have plenty of muslin squares left over from my gigantic marmalade cook-up in February. We had a few empty honey jars (there can't be more than 8lb in these two frames, probably less than 7lb), a sharp knife, a good-sized pyrex bowl, and a regular kitchen seive. I also had to borrow the communal giant preserving pan from next door, so it wasn't technically just equipment we already had in our own kitchen.
The first step is to remove all the comb from the wooden frames by cutting it out over the bowl.
It was easiest to do this is in sections, as the weight of the honey here dropping out can make quite a mess.
The knife sliced thorough the warm comb really easily, no need to heat the knife in warm water even.
With the two frames emptied of all their contents we tried to scrape every last drip from the frames into the bowl.
The huge pan was filled with heated water, then the dish was suspended in it. It's very important not to heat the comb directly because natural wax has a specific 'flashpoint' - if a certain temperature is reached (I forget the exact temp, but it's higher than boiling water) it would just instantly combust - along with all our eyebrows, presumably!
While I attended to the melting, the kids spent a happy few minutes picking over the 'bones' of the empty frames, with sticky fingers and spoons!
I put a plate over the pyrex bowl to keep the heat in and sliced up the comb into small pieces as it softened.
After a few minutes it had all become very soft and easily stirred.
Before long practically every last bit had completely melted, but the wax was quickly solidifying on the surface.
I removed the bowl from the pan and the top surface set very quickly as the air temperature cooled the wax - wax is less dense than honey (as is any dross in it - lumps of pollen, bee legs, etc) so that all floats to the surface, then sets solid. We left it like this for a while for the wax to solidify, then we could continue.
With the wax on the surface cool now, it would be simple to separate from the honey...
... and it just lifted off!
As there was not much wax (surprisingly little, actually), it all broke up as I lifted it off. I removed every bit and placed it with the empty frames for the bees to clean up later.
I returned the honey to the warm water to make it as runny as possible - it still needs to be filtered and it'll be quicker the more runny it is.
I spooned it into the seive, containing two squares of muslin on top of each other, and we funnelled it directly into the empty (and recently sterilised) honey jars.
I'm not much of a honey expert, but it looked just perfect as it poured in.
As soon as one jar was filled up to the 1lb line, we switched to the next one.
Before long. with one of us holding the seive over the funnel and the other refilling it from the bowl, the whole process was almost over - in the end we had about 6 and a half pounds of honey from the two frames (the last few dribbles in the large jar took ages to finish).
We selected two as gifts for the grandparents (with our own home-made labels, of course!), leaving us with a whole 4 and a half pounds of honey - so exciting and so much easier than we were expecting!

[NB - in case anyone reading this is worried, I am fully aware that these labels shown are legally not suitable for sale. Besides, honey which has been artificially heated like this should only be sold as 'overheated' under the title of 'bakers honey'. It is useable and safe but the heating process has altered it and it would normally now only be used for cooking purposes. Therefore this is not a suitable process for commercial honey production, even on a small scale, but is a safe way of extracting a small quantity for personal use, when in a pinch!]

Preparing a Nuc for Transport

Saturday 12th June

Blue 1 is being collected tomorrow morning so I need to seal up the front entrance tonight, when all the bees in the colony are tucked up inside for the night.
10:00 pm There was no sign of movement from the outside at all - I came out about an hour earlier and surprisingly some bees were still flying then.I stuffed a small chunk of foam padding into the entrance hole.
My proper hive strap is too large to surround this small nuc. I should find a more professional-looking solution for another time, but for now I just secured it tight with packing tape, wound round a few times. It's not a pretty solution, but it makes sure that nothing could accidentally come loose tomorrow.
