May be a bit early to ask but what is everyone finding?
I have very few losses, just a couple of nucs I did not expect to overwinter anyway.
That's the upside. The downside is that colonies are smaller than I would like for the time of year.
I have lots on 3-4 frames of bees and very few on 6+ which would be ideal for March.
My nucs in particular are a lot smaller than I would like.
Only one drone layer out of 35 checked which is good and the rest all have some brood.
I would expect most of these colonies to be built up to decent strength by mid May.
No oil seed rape that I know of in the area this year so the sycamore late May is usually the first decent nectar flow.

My colonies had high mite levels early on last summer so I imagine this is a knock on effect from that.
I treated with Thymol/Apiguard in August, and Oxalic mid December.
Mite levels were high in mid July when I sampled colonies.
