Where to start? I have 3 baby muscovy ducks - one is twice as big as the others and a few weeks older. I have them in whaat we call our "teenager dorm" (out of the brooder but in a small coop/run with a heat lamp) with chickens & 2 poults. The only other inhabitant is our mature bantam rooster, Batman. So a few days ago the little ducks who are just getting feathers started goign bald on their backs. I hadn't noticed thaat witht he slightly older one who is now fully featehred. (any guesses yet?) So today I noticed Trooper the oldest of the scovy trio limping a bit. I picked him up and he looks ok and didn't flinch when I inspected him head to toe. Now he's laying in the yard...just laying there when everyone else is up pecking/walking around. So...earlier today I saw Batman mating the scovy baby. Now I think I know why the other scovies are going bald on their backs. Yes, Batman used to have a flock of his own girls, but when one of those girls turned into a big huge dominant standard size roo we moved Batman to the dorm. He does have a flock of 4 bantams pullets, but they are not mature yet and I guess the muscovies are getting the brunt of the behavior? Shall I attempt to isolate the roo or the scovies? I'm not sure if it's wide to put the ducklings in the big coop yet? It holds 4 adult scovies, 1 adult injured turkey (who sleeps alone so the adult scovies don't eat on her), one big roo, and 9 standard hens. Trooper would likely be big enough but the littler ones are pretty tiny. What I really need is my hubby to come hoem and build me 2 new coops.
