I know this question has probably been asked many times, but I can't seem to find the answer so going to ask again. I have hens in Blue, Black, Splash and recently got a Partridge hen and rooster, am I correct in thinking I can't use this rooster on anything except the Black hen and the Partridge? Or maybe not even the Black??? These are LF Cochins but I assume the genetics are the same for all birds. I don't want to raise "muckledy duns" but only want to stay with recognized colors. I'm thinking my only option is to get a second roo with B/B/S gene???? Thanks for any help, have a blessed day.
