We are brand new to chickens. Bought 6 various chicks at TSC. I'm pretty sure 2 are red sex-linked. I don't have pics of those, but they started out yellow and are slowly turning red. I have 2 that look like chipmunks, so cute. Advertised as Ameracaunas. Pics are below. There are 2 black and silvery white. Not especially attractive at this point, either in looks or attitude. They are the largest. These were advertised as pullets. We got all of these chicks 2 weeks ago, so the oldest they could be is maybe a few days over 3 weeks. The black chicks have red combs and are beginning to get wattles. Can you guys identify the breed and sex of the pics I have posted? Thanks for any help!
