Turns out I have a Pearl White Leghorn rooster, but he does not crow and is not interested in breeding. I thought he was a she because he looks almost identical to the girls. He does not have any fancy plumage and is about the same size, but the other day when I was cleaning the coop he confronted me as only roosters do and I started looking closer at him and realize he was not a she. I have 130 chickens including 40 pearl white leghorns and I thought he was just one of the girls, but after looking closer I realized his spurs are growing and his neck feathers are a bit finer and longer, his comb and waddle are bigger and the coloring of his comb and waddle and face is much redder. Also, his comb stands up much straighter than the hens. He was hatched on March 14, 2010 so he is now over 7 months old. I would think he would be crowing already and definitely interested in the hens, which he is not. My much younger roosters are much more advanced than him. He lives in a coop with a dominant Maran rooster, so I am wondering if that my have something to do with his immature male drive. Will he ever mature? I am really happy to have a leghorn rooster, but am wondering if I will ever see any offspring from him.
