strange one over night
checked the colony yesterday, all seemed okay, am running a 14x12 brood with just one super on at the moment.
then out at around 22:00 last night to shut the hens in, low droning from the colony and the hive entrance was packed with bees - not bearding all over the front of the bb, just in the entrance. was probably about 10-15c at the time, so not massively hot. checked this morning, a fair number of dead bees out the front this morning. BB is set up hot ( ie, frames set parallel to the hive entrance ) but I'm surprised if it was that hot with a fully loaded BB and I didn't think it was a sign of imm. swarming.
any ideas gurus ?
thanks in advance
