This spring, I'd like to get a few turkeys, and possibly a couple of ducks. I already have a layer coop and a meat bird tractor, so my wife's patience for me building bird housing isn't going to allow for much more. I'm thinking of building a good sized fenced in area with some sort of shelter at one end, and putting the turkeys, ducks, and whatever other non-chicken type bird I decide to get in it. Not considering space requirements, can these birds be housed together? Will they all do alright on the same feed? How about predators? Are they a problem for adult sized turkeys, or do critters leave them alone?
