So, I'm just wondering how much feed a chicken should be eating in a day? I have a 7 pound feeder, that I have to fill 2 times a week, but I also throw out some feed for them when they come out of the coop. So, I really don't know how much they TRULY need a day. 1/2 cup per chicken???? 1 cup per chicken??? They also get to free range in my yard more days than not. I'm mainly asking so I can determine how much food to buy at a time, and for when we go on vacations and I need to have someone keep an eye on them for me. Thanks!
