I have/had both Pekins and Khakis, and they stayed on the ground. Neither would walk up the ramp into the coop, and even slept on the bare ground. Two weekends ago I adopted 4 female muscovy.. I've seen a Muscovy on a roost, and tonight 3 of 4 are in the coop with the chickens. Can I expect them to lay their eggs in the same nests in the coop? Also I have a Pekin Drake, I would assume he can fertilize the muscovy females too? Is there a way to tell the difference between Pekin and Muscovy? How abput Khaki? Don't have any Khakis at the moment but have 7 baking in the incubator now.
