Found a nice NPIP poultry breeder close by and was able to purchase 5 young Black Orpingtons...3 pullets and 2 Roos. Guessing the birds are about 4-6 months old...very pretty and very healthy looking. As I do not have a quarantine pen, I went ahead and introduced them to the existing flock and everything is going well. The new ones have already found the feed bins and water buckets. When should I expect the Roos to start crowing and doing their " I am a MAN bird " thing ?
