I have 7 chicks that hatched 2-16. Dad is buff orpington,mom is light brahma. The chicks therefore are sexlinks. I'm confused about one of them though. It started off yellow down,and white feathers coming in. But after the first week,they started getting darker. Is this a male or female? If female,why did it start off,looking like a male? One in question is the first 2. There are 2 buffs and 4 whites. This is the only one that looks like this.
