I am soon to get some more chickens after a predator killed two thirds of my flock, and I think I may want to add ducks to the mix. I am aware of how ducks can swim and chickens can't, and I have heard that chick starter is not good for ducks due to some medications in it. My question is: Will I be able to make a coop that chickens and ducks can live in, and what kind of food can they both eat? Also, can the ducks eat the same layer food as chickens when they get older? Thanks for your help!
