This is our first offspring. My rooster is (supposedly) Black Australorp. My three hens are: Speckled Sussex, Buff Orpington, and Buff Brahma. My Brahma was my broody; so I'm fairly sure she isn't the biological mama. She had been broody for at least a month before I left her one egg. Assuming, by the polka-dots that the Speckled Sussex is bio mom. The rooster is gi-normous. The only one I have EVER seen as large as him was a Jersey Giant. This "chic" is 10 weeks old. Should I expect crowing soon or eggs.
