Aw! I haven't been getting notifications on this thread for some reason. Beck is adorable! I'm glad I could help you with him. It's usually a bad idea to brood ducks and chicks together because chicks need a dry environment and ducks always end up with a wet one. It really would be best to get another duck if you can find any ducklings locally. When he grows up he (if it's a he) will think he's a chicken and will mount your poor hens which will probably result in death for them. If it's a she it will probably be mean to your chickens. I think if you want to keep it you should get it a buddy while it's young. Its cute that the chicks like him.
