I just have some backyard chickens. Nothing special genetics wise just special to me lol. Most of them are RIR. I also have two Buff Orps, three Bantam Cochin and an EE that are laying right now. Im working on incubating and have learned a lot from my first try. lol. Have two chicks from that try. Anyway giving the bator another try and this time I was picky about the eggs I put in. I have four of my EE and the rest I only put in the darkest eggs. Am I correct in thinking this will produce hens that carry a darker color egg gene? And will probably eliminate the RIR X BO crosses? I don't mind if I get those crosses. Im going for egg color. Or does someone have BO that lay very dark eggs?
