So, I bought this Delaware pullet and a leghorn pullet in march to add to my existing flock of two ameraucanas and three silkies, but I noticed that my Delaware is growing very fast and is twice the size of the leghorn. Its wattles and comb turned red at an earlier age than any of my other girls. Can anyone tell me if this is a pullet or a cockerel. I'm in highschool and an FFA officer and these are my SAE an I do not know how to handle a rooster. "She" also has barring on her tail and I thought I read something about hen have solid black tails while roosters have barring. Thanks for any help.
