I have feeders placed all over the chicken yard during the day and put them up at night so bully’s can’t keep everyone from eating. Chickens eat what they need, they don’t overeat so rationing food is not a good plan, I have 2 feral cats that live with the chickens and have never had a rodent problem. If the squirrels became to much of a problem I would shoot them but they prefer cat food over chicken food.
