We bought a chicken about a month ago from a reputable source. The seller said she was around 20 weeks like all of other black sex links he kept together. At that time some were laying and some weren't but he wasn't sure which were and which weren't b/c there were a lot of them living together. He grabbed us one out of the bunch and put her in the box for us to take home. At first I thought she was young and not laying b/c she didn't have a comb or wattle grown in. On further inspection at home, I saw she had wattle on one side and not the other. Is it possible she is older then I think and that her wattle/comb were henpecked in her former home? If so, will that grow back in? We have had her for a month and she still has not produced an egg. Thoughts????
