When I bought my goat today, the lady there had SEVERAL one week old chicks of various breeds. She gave me six for free. One is half white leghorn and half lavender Ameraucana. The chick looks SO SMALL for it's wing size! I think she said the two buff are brahma. The other white is a leghorn. The silver and dark brown are siblings, mother is a barred rock. Let me hazard a guess here... I predict that the silver is a boy (duh, right lol), one buff is a boy, and the others are all girls EDIT - a barred rock is the mother of only the two chicks. (brown one and silver one)... sorry about any confusion.
