That is exactly why I went with all non crested roosters this year. Any rooster can go with any hen. it makes the housing issue SO much easier. Sorry for your little ones tho!9 chicks hatched!
And I have to decide if I want to keep crested birds at all, as keeping separate groups isn't how I envisioned keeping poultry. It's a big enough pest keeping my bantams in. I have a ton of experience with genetic issues; I bred horses for a while, and I had a lethal gene pop up. But do I want to manage this for chickens?
