I have 9 babies. 5 of them are definitely cockerels. I have 3 pullets. We just are not sure about this little Am. baby. It hangs out with the other pullets, and does not participate in the sparing that the little baby roos do. But, it is really big, has a big head and really dark feathers. I have never had a wheaton am before, so I don't know what it is. I was waiting for it to get "drumsticky", but don't really know what I am looking for. It is 7 weeks old. I am soooo hoping it is a pullet, but will keep it even if it is a roo. Thanks for your help!!
