Thank you so much for the answer! I'll keep all of that in mind. I don't breed any bird that seems to be weak in any way, my first goal is always for healthy, long-lived birds above anything else.

My breed is called the Dalmatian Bantam, hints why I used these breeds. Really I'm using any bantam that creates the paint pattern. However, I'm still in the very beginning phases of my project.

Again, thanks so much for the answers! : )
