I have done several splits this year and out of 8 splits, I have 2 that won't except queens. I've tried twice and I go back 2 weeks latter and can't find new eggs or brood or queen. When I put in queens I put in a frame of brood and frame of honey and pollen, put in queen wait 4 days and ( I have tape over the sugar plug) then remove tape so bees can let her out. Is there anything I can do to make this work? What I'm I doing wrong? Thanks!!!!!
