Im a newbie. We have 12 layers, 2 roosters and 4 bantam show birds. They have a fenced area that is appx 40x40' but they choose to hang out in the rest of the yard instead. Id love to add some ducks (layers/pets) this spring. Id like the ducks to stay in back, but the chickens dont so I have no idea what to do. Should the ducks be penned up in the main run at night? Is that enough, do they need a coop? Thanks for any advice Regina From Front "Run" measure 16x16', 4 bantams stay in at all times, all other birds free-range all day. From back - open area measures appx 50x50' tall building has secure area with 3x7' space for more roosting/boxes. main coop - 2 long 2x4s for roosting + 6 boxes.
