Re: can you go in your hives too much?
I go into them every week during the spring & early summer. Helps me keep moving frames so they pull more comb and I increase the brood comb. Also seems like if you are not watching closely, swarm time happens really easily.
Since I am going foundationless, I cannot place an empty hive box with empty frames on top and hope the bees pull comb and start storing honey. Or at least it has not worked so far .
I might set them back three days each week, but if they swarm from a nuc, you are set back a few weeks waiting for that queen to mate and start laying again. So it is worth it in my opinion.
Started 9/13, building slowly, now @ 12 Lang hives and no treatment yet
