Re: In need of second opinion
Nice looking swarm. It looks like they found a bird house and are doing well. You could leave them alone and see if they make it to Spring and then switch them over to a Lang or do it now and try feeding them. I am sure people will have a fit because I said to leave them alone but if they make it you will know they are good survivor stock. You will probably get 10 other opinions so it will boil down to what you want to do. Do you have other hives?
