Hello, I've been a long time lurker and finally got the birds so now I can post LOL. 8 chicks and 6 ducks, all 2 weeks old, came to live with us on Mother's Day. Now getting ready to build the coop. I know they each need their own coops, mostly because ducks are very messy. Instead of building 2 coops can I build 1 big one with a divider? Will they know to go to the right house at night or will they get mixed up and I will have ducks in with my chickens and vice versa? They will be free range for the most part, don't know if that makes a difference or not. Thanks!
