Queen Bee
Sat watching the hive today and seen three bees walk out then back in with very deformed wings. Should I be worried about this at the moment?
I think you should put in an inspection board for a few days to get a mite drop count. Then take it from there ...
... there will be more sage advice than I can offer, but I suspect that it might prove prudent to anticipate an Oxalic treatment in a month or so.
