I've tried keeping turkeys like chickens. They don't like it! Turkeys like the great outdoors. The building that they prefer to use on my property is more of a lean-to open front shelter with perches for them to get off the ground at night. One word of warning...perches should not be more than 18 inches off the ground because as these birds get bigger...and they will get bigger,... a big drop from the perch to the ground will hurt them eventually. Injuries to the feet and legs can lead to more serious problems like infection and swollen feet (Brumblefoot). The shelter does not have to be very big for healthy, natural, good-natured birds,,,it is much more important to have the largest pen you can afford to make for them to forage bugs and plants...also to minimize bacteria buildup from constant exposure to their own droppings. Good Luck!
