I have (4) - 3 week old Serama chicks hatched in an incubator. I know it is very early but these babies seem to really be getting large combs with some reddish coloring already. I am seeing 3 roosters and a hen....The first one is looking like a hen and the next three all look like little roos to me. Any insight? Do seramas show their gender early by any chance? 3 pictures of each chick... thanks!
