The only part or our yard that is fenced has our swimming pool in it. I had ducks before chickens and we cut a hole in the fence to the coop so they could come and go. When I got chickens I blocked off the duck door. My hens are 4 and I really think they'd enjoy getting out of the coop to forage. Could they learn to avoid the pool or am I just asking for trouble? I wouldn't them out without supervision.
