Also I'm not sure how you would be sure the would be sterile. Insulting my bird's for god sakes! That's just low.
Haha. I say sterile because that is what I have read about these crosses in the past. It happens with pheasant and chicken crosses quite a bit. The baby grows fine, but cant have their own babies. Same with Horse-donkey crosses, and tigons/ligers. With tigons and ligers, the females are fertile whereas the males are sterile.
