The rooster is supposed to be a Serama but he looks to big to me. He is a very good roo. he finds food for the hens and watches for hawks when ranging. I have no idea about the other two. Got all three because my daughter thought they are adorable and I thought the hens would brood for me this spring. My other chickens are Buff O., RIR, Leghorn, and mongrel RIR/lavenvlder mixed. Look like little T Rex when they run.
