(1)- when would it be time to mate them? (2)- do you think they would make good meat birds? (3)- Past ordered my birds, want to try hatching? First time useing white plymonth rocks ordered 25 form McMurray good looking birds. (4)- Have you had white rocks? (5)-Should I keep a white rock roo for mateing too? Have to keep all my birds in pens for there safety can not free run. Would have to build another tractor for white roo. THANK YOU! always been a good forum to get good info.
