Re: Direct release, or bee release...And feeder?
In directly releasing the queen I would suggest opening the queen cage and than placing it in the TBH and quickly closing the hive. Last week I got to watch one of my queens fly around for a long 20 seconds (I think she landed back in the hive but am not sure). If I do a direct release in the future the whole cage is going to be left in the hive for a while.
PS How big are the hives? They seem a bit small, but that may be just the photo.
