Right now, I have broodies in the two coops. I don't want to move any of them as ducks can be very picky about that. Or else I'd put all of them in the same coop, and put the others in the second one. Right now one is for the regular ducks, and the other for the Muscovy.I need to do the same. I had one chick killed this year, the nest box I had mom in was a plastic one a bit smaller than my normal ones and think she stepped on it.
