I want to get a hanging feeder to put out in my chickens' run, hanging from the "ceiling", but I'm wondering, how early is too young to not have them eating through the night? (Did that make sense?) If their food is outside, and they are inside, obviously they won't be eating. Chicks with their mom don't eat all night, I assume. Once it is warm in the night, probably a couple more weeks, I will leave their chicken door open at night so they can come out and eat as soon as they're ready in the morning. Their house is in a pretty secure run, so I'm hoping this will be ok. The motivating factor in this is that, for the last few days, in the morning, they have emptied their chick feeders and knocked them over. Any suggestions?
