I am smi new to the mass production of queens and this is my frist go round! I have constructed a Queen Rearing Box the size of a standard Nuc. I split it down the center and made a modified queen excluder to fit like a standard frame (just no gaps so queen cant pass) and each side allows 2 frames. I made 2 entrances in oposing Sides and ends. and constructed a rearing frame for cups with 3 rails each, so I can raise 6 cup rails of queens. Am I on the right track?
