Hi Kirko,
I have two hives . They are doing very well, a lot of bees, queens are laying, they are bringing pollen although there is nothing green yet.
When you have so early spring, you have situation that wintered bees will die before summer. It nees time that new bees emerge and colony start to grow. During this time tehre no reason to give tehm foundations or more room.
Several days ago when I was checking on them there was quiet a lot of them hanging under the inner covers. I was wondering if they are the young ones who have nothing to do. .
Surely they are doing their job there, what ever it is.
When bees build combs they must be over 12 days old. They are then foraging age. If bees have nothing to do, comb building is the last what they do.
Bees make new combs only if
1) they need space for eggs
2) cells are going to be filled with nectar and they need more storeroom.
Otherwise bees save energy and do not make combs beforehand.
In my country cardens and dandelions are blooming before they want to draw even one foundation.
