I have 7 Banty chicks, which are almost 9 weeks old now. We recently heard one of them attempt crowing, so I'm pretty sure we have a rooster in our midst! Is this a usual age for them to start crowing? They are living in a 10x12 converted brick horse stall, with an automatic door, and a 12x12 outdoor pen. Is this big enough for awhile? When should I expect the rooster to try doing the deed, etc? At what age will girls start laying? I have 2 silkies, 2 that I think are barred rocks, and 3 e-e's. I believe the rooster is a e-e. All are Bantams.
