Chickens and Ducks in same coop?

[Casey777]

My dad built a coop for my chickens and its fairly large i wanted to know if i could mix my 2 female chickens with my ducks. I am getting Pekin Duck eggs straight run so i don't know if they will be females or males but i was wondering if they would fight or it would be a bad idea. If it is a bad idea then can someone send me maybe like a blueprint or a design for a coop please and thank you

I do not have chickens and ducks, but I personally know a man who raises chickens, ducks and turkeys and they are all in the same run area. I have also heard other people on this site comment about keeping them together without problems.
