I'm new to chickens (mine are about 2 months old). We have food and water inside the coop. Every day I fill a tray with food to leave in the pen for them. Can I just leave the one feeder inside and not put any outside? THey've never gone back in the coop once they go out in the morning until about 8pm they go back in. I'm afraid they won't eat enough if I don't put some outside as well. thanks!
