I hatched out 7 sussex on June 1st, I believe that I have 3 roosters in the lot. I live in town and I am not allowed to have roosters. I am not opposed to sending the boys to freezer camp, but I would like to wait as long as possible. They still seem kind of skinny, but I know at least one is testing his voice. Not a crow by any means, but I am nervous it is soon to come. Does anyone have a good estimate as to when the boys get their real voice?
