I have 10 Partridge rock chicks. They were supposed to be just over two weeks old when I got them. I have had them for about a week now. Some are much bigger and gregarious than the others. Also, thos bigger chicks have tails and well developed primary flight feather. Would those be roos? The other are much smaller and either don't really have a tail, or it's much smaller. Also, the primaries are coloring in dark instead of retaining all pattern like the smaller ones. Anyway, I hope someone has had success with guessing at this.
Thanks!
