I have a mutt breed chick. Her mother is all black and not sure who the father is but the roosters r all dark. My chick has 2 siblings which both are mostly black. I have never seen a snow white chick before. when she first hatched her beak was blue but now it is turning more yellow. She also had 2 thin black stripes down her back. Let me know if any of you have seen a white chick before. I'll post pics tonight.
