Did a walk away split three weeks ago during some lovely weather. The queen went with the "new" hive. Checked on them today and have a couple of concerns. Examined all frames closely and noticed two bees with deformed wings ( yikes), also a frame containing about 50 capped bood on the outermost of the brood nest had at least a dozen bees that had died while trying to emerge. Some had tongues sticking out, all looked pretty well formed, no sunken caps, odor ect... The other wrinkle is the temps got down to a completely unexpected 4 below freezing 4 nights ago.
my questions are these:
1) are the deformed wings and the death of the pupae realted?
2) do I have 2 problems going on here DWV and chilled brood?
3) are 2 bees with deformed wings a sign that the whole colony is in trouble?
This split was from a very strong hive going into the winter. It was treated last fall for mites, AFB and nosema. I am trying to use IPM and less chemicals going forward and have installed screened bottm boards and did hive reversals and splits this spring. Queen looks like she is laying well and has a nice brood pattern. I know others have posted similar threads but none seemed to have both my issues. Thanks so much in advance for any insight. ps I've only been at this a couple of years.
