Out of the two buff Brahma pullets we ordered, one turned into this: He is HUGE! Both the roo and those two SF's are the same age. They're about 17 weeks now. How much longer will he keep growing? Is he supposed to be this large? He's a lot bigger than the Brahma pullet we got with him, and twice the size of all of our other chicks. When should I expect him to start crowing? So far, not a peep. I live in a suburb but I am really hoping to keep him... This is the pullet, isn't she pretty?
