Hello, first thank you everyone who posts, alot of valuable info in here. Anyways, we just added two more chicks to our flock and we got them from a straight run, and cant tell if ones a roo. The 'suspect'(chick #1) has a protective, bold personality over the other chick(chick #2), sometimes when we go to pick them up chick#1 will stand between our hand and the chick#2, also it will "hover" over chick#2 like its guarding it. Chick#2 is more shy and timid. They are still pretty young for me at least to be able to tell them apart, certain things stick out, chick#1 is a little more mature than #2, is more feathered, tail feathers are longer, even looks a little bigger, though its hard to tell for sure. Hoping anyone out there has an opinion on if they think #1 is a roo. Any replies are very appreciated. Pictures are posted a couple replies down. Thanks!!
