As long as the parents are in good health and there is no major inbreeding, mixes are usually healthy unless there is something major wrong in the mix which would lead to embryonic death in most cases. I personally do not agree with mixing breeds like that... I believe in bettering a line. If you just want to hatch chicks I would purchase some from a local breeder.Thank you!! I'm just concerned with its breeding...its daddy is a showgirl and momma...I'm thinking is a RIR/bantam mix. That's a lot of mixing of breeds for a chick...and I have tons of eggs in incubator coming soon. And the only rooster is a showgirl...and lots of mixes of momma hens. I'm just a worried chicken momma...and don't want nothin to be wrong
