I'm a poultry newbie & any opinions will be greatly appreciated! These 2 are supposd to be an Ameraucana (but more likely an EE), and a Barred Rock. The coloration on the BR leads me to believe maybe it's a black sex-link?? My biggest concern is that I'm thinking they're Roos. They are 5 1/2 weeks old. Thoughts on sexes & breeds please!!?? They were purchdes @ TSC.
