I've had ducks this year, but due to my setup, they cause quite a mess, so I'm considering getting chickens (and possibly quail, or a couple turkeys, but let's disregard those for now) next spring instead. Because of my setup, it's hard to get a good laying duck that doesn't require lots of space but produces lots of meat. Chickens are much easier to find locally. That's why I am considering them. My current setup is this: A duck coop divided into 2- one half is a wood floor, and closed space, with bedding. 1 half is a dirt floor with open sides, but a roof. There are no roosts, but there is a 1ftx4ft shelf. 1 half is 24 sq ft, in total it makes for 48 sq ft of coop space. It is 4'-4'6'' tall. This is beside a horse shed (run-in or 3-sided shed) that is covered and provides a dry area even with snow, and an outdoor run area, away from the shed, but attached to the shed. The run area is 300 sq ft with a 2-layered 4.5ft tall fence. I'm wondering what adjustments need to be mad for chickens? I keep the bedding, feed, oyster shell, and grit in the shed, and this works well as they're covered and protected. I was considering removing the shelf (1'x4') and making it into the base for my quail home. Then taking the dirt floor and making it into a wood floor, and connected the divided halves of the coop, as well as covering the sides of the outdoor area of the coop (except for the side towards the shed, with the coop door). Is this a good idea? Should I add nest boxes? How much roost space do I need? I'm hoping to fit between 5 and 15 or perhaps 20 chickens in here. If I get turkeys, the poults will live in the coop until they're older, then they will live outside or in my 20sqft dog house.
