I have a lavender cuckoo roo over solid lavender hen. I'm getting both cuckoo and solids which tells me he is single barred. This makes it hard to sell young chicks bc I'm not sure until they feather out if they are cuckoo or solid. I'm not going to continue with this breeding bc of this problem. But I have hatched out a bunch of chicks that I'd like to sell and not have to hold onto until I can tell what they will be.
