Hello,

I installed two different packages this spring. One had a dead queen on arrival and we had to get a new queen.

We ended up with one strong hive and one weak. We stopped feeding the strong hive but continued feeding the weak hive which caused the weak hive to be robbed. We stopped feeding and want to install a robber screen.

Our question is; When is the right time of day to install the screen, early, late or it doesn't matter?

Thanks for your help.

Dan
