2 questions, I have chickens, guineas, and ducks that I purchased at the same time and I've kept together for the 2 weeks I have had them. Will I always be able to keep them together without problems? Second, chicks and guineas are almost totally feathered and supposedly should be about 4-5 weeks old. My ducks (mallard) are much larger than the chicks and guineas, but the ducks hardly have any feathers. Can they go out in my coop? My coup is a little more sheltered than most, I think. I have a shedrow style barn with added solid wood divisions between each stall. We used mesh fence panels to build a coop in the back of a stall, so they're sheltered on 3 sides and have an overhang well over the top of them. There's a heat lamp in the back. Are they okay to go out there? They are getting so big the smell from the trough is getting too much for the garage!
