Glad to see I am not the only one with this problem. I am also new to guinea fowl. I had four and was told how to teach them where home is. That wasn't a problem. Kept them in coop for six weeks. Finally, got them to go out. Need the coop for my bantam chickens. Everyone told me guineas were wild and would roost in trees, that it was hard to get them to stay in a coop. Well, mine sleep on the ground. The only one who ever flew up in a tree got ate by a coon while sleeping on the ground. Don't know how to train them to get up there. Thought about getting some older birds who already roost in trees. Mine are four months old. Got them to make noise when something is around my girls 4H chickens, so I don't want them cooped up. Any idea of to get them to roost in a tree. We have many trees with lower branches. Thanks
