We were given these chix by a neighbor, who said they are "meat birds," but I'm beginning to suspect they might not be. They look huge to me, but I'm new to raising chickens. Earl started crowing about a month ago, is exhibiting very protective/aggressive behaviour, and actively tries to mate with Lucille every chance he gets. Lucille has not laid any eggs yet, but I don't have a great nest box for her yet. They are somewhere between 8-10 months old. Meet Earl and Lucille: White rocks? White leghorns? Something else?
