First off just wanted to say hi been away from beekeeping for some 20 yrs. so I'm not totally green. Does anyone know why my Strongest hive I own 18 frames full of bees to he point of overflowing I added a shallow supper 10 frames not drawn out and there not interested at all. I didn't put a queen excluder and they still don't want anything to do with it. Does anyone have an idea why?
