They need to be able to get out of the cold . Mine have access in and out doors all season. When the temps drop real cold I close them in . A covered pen is a must , they will fly away if they are full winged . You can clip there wing feathers , for the season , If you have a open topped pen., But I find they do the best when they are able to fly . I feed wheat, waterfowl pellets, fish pellets, mixed grains, corn , greens, and what ever they have access to when they are out on the pond.
They produce best in the second year . The hen nest in a raised nest box. The hens do a great job of raising there broods. You can also incubate the eggs, and raise them yourself , if you wish to do that. Enjoy ...
