I know this is a stupid question, but I have to ask. I see many members use automatic feeders. Will chickens only eat what they need if they are given an unlimited supply of food? I've just been giving mine a limited ration everyday to make sure they don't become overweight, but if there is an easier way, I'm open to it, lol. Oh, I forgot to mention, I know chicks need an unlimited supply because they are growing, my question is about the full grown gals.
