I have been thinking long and hard about what chickens to breed together. I have a result of 3.
Buff Brahma
Pros: The size, demeanor, the feather colors, the egg color.
Cons: They may not survive New Mexico summers without extra care.
Chocolate Orpington
Pros: the feather colors, the egg color, the size, single comb
Cons: I have not had success with any orpintons, and chocolate orpingtons are hard to find.
Blue Cochin
Pros: single comb, egg color, feather color, size
Cons: They will have trouble in NM summers.
If anybody has breeds close to this, that have not been previously mentioned by
@Northwest_Wannabe I would love to know
