There is a huge open pasture with some forests, short grass feilds, semi-forests, and a pond. I was thinking I could save feed, make the chickens happier, and entertain me by letting the chickens free range while I was watching them while fishing or taking a strole. Would I have to clip their little chicken wings? There are coyotes but Ithink there are in the next pasture across the road behind it and we just hear them at night. Is this a good idea considering the facts?
