As a chicken newbie, I just started out with 6 chicks. I have these two RIRs and they are both nearly 12 weeks. A is actually a bit smaller than B. Their combs are very similar, but the tails have me wondering. Pullet or cockerel? Thoughts?
Tail feathers are a good indicator also people on this and most American breeds, the hens points more towards the back with slight rise while you'll get a big arc and longer on the males that gets more noticeable as they grow
