Will a chick with white/yellow patches grow up all black? I assumed it would be like its mum and dad who were both black. He is 1/4 D'uccle 3/4 Ameraucana so Could this be a d'uccle colour showing up? Any predictions welcome! Here is chick here is (a bad pic of) bio-mummy The dad was also all black, a pea comb, head poof and beard.
