Thank you. At the moment I have a large dog house or 'duck hut' as we call it for my Rouens/Khakis which I thought they could share, but given the size of the male muscovy I think I'm going to need to set up another housing area for them, especially during the introductory period. I'll have to set up something temporary, but it won't be insulated at this point. I have lots of scrap lumber so I should be able to throw a lean to style together with ventilation at the top.They don't need anything fancy just something secure for night time protection from preds, even a large dog house would work, but it will have to have plenty of ventilation, they can get respiratory problems from breathing the damp air in an enclosed coop. they need 4sq' each I believe, but make it as large as you can because when the girls begin to lay they like their privacy.
I also read that they need different feed than chickens? We can't get feed here specifically for ducks so we just feed them chicken layer pellets. Any suggestions on this?
