Four hives started from packages on April 30th. I left them alone on cold snowy days, but now the days are into the 60's and 70's and the nights are only getting down to the low 40's. I like to look at them and check out eggs and brood every other day. I usually give them a little smoke before opening them up. Will intruding often like this make them mean, or will it get them accustomed to being inspected?
I worry about chilling the brood, so if there is a breeze, I take a quick look at both sides and put the frames back into the hive. Does the larvae also need to be kept warm, or just the brood?
