Had time for a cursory inspection on Friday. The aforementioned colony that had filled the upturned poly feeder has only slightly drawn out a couple of frames of the super of foundation I added. Instead they have focused on filling the space between the lower shallow box and the new super with more brace comb.
Popped the preexisting shallow off and it's packed with uncharged queen cups...
3 neighbouring colonies are booming. Drones were spilling out of one hive (already on 3 shallows and a BB) - first time I've seen them in my apiary, as this is the 1st time I've had well established colonies.
Had a look at the other colonies by tipping up boxes and looking underneath, as it was 13c, so didn't feel appropriate to pull out frames.
Plenty of drone brood, no signs of varroa, didn't see any obvious queen cells, but 4 colonies are now packed with bees. So difficult to really see.
There are so many bees it took longer than usual to put the hives back together.
I replaced the undrawn super with a drawn one. I also added a drawn super to all the other strong colonies, which were over spilling with bees. I also added a BB of undrawn foundation under the existing BB for the strongest colonies. Unfortunately, I don't have drawn brood comb. My thinking being that they really need space, so at least that have some opportunity to expand the brood nest as the incoming nectar increases.
Usually, I can only get to the apiary at weekends, so my priority was to ensure they at least have space until I can do a proper inspection, when the temperature improves.
As it's a bank holiday, I do have time to look again tomorrow, it will be 14c.
Due to heavy wasp attacks last autumn, 1 colony is tiny and needs a boost. I'm considering inspecting the strongest colonies tomorrow and pulling out some frames if sealed brood and popping them in the tiny colony.
Any thoughts on all this?
Next 7 days weather forecast: low 7c, high 17c
