I'm very new to this and would like to know What will happen when my 6 Guineas (about 16 weeks now) realize they can fly? Will they still go into the coop at nite with the 5 Ducks ? So far they do. They free Range with the other chicks. There is not a top on the area they are out in during the day. Just a fenced in area. I realize my question is not very clear.
