Hi all, where I live we are not allowed roosters. We got our chicks from an individual breeder. Told they were all hens, but this morning our frizzle began to crow. I am going to post pictures. Is this a roo or a hen?

that is a cockerel

Same age Rhode Island Red... Is her waddle and comb too developed to be a hen? Also is the dominant chicken

very pretty production red pullet
