First... Our flock consists of 7 - Three we got at the beginning of March, two a month later, and two about mid May. The drake come from the first batch, and is trying (and I think was successful) to mate with the youngest - isn't this too young? He is so amorous, does it die down? Those two youngest are Khaki's, when will I be able to tell the sex? We are gearing up to redo our coop - we now have a total of 7 ducks, and 10 chickens. I was thinking about putting the duck nesting boxes on the floor under the chicken nesting boxes, does this work? Or, would it be better to set up their area in the outside run that is attached to the coop? Thank you!
