Title says it all. I bought my girls a nice stainless steel hanging feeder, a 12 pound one. I have 17 birds total eating out of it. It seems like a full feeder is lasting me about a day and a half and that's with a couple handfuls of corn tossed into the shavings for scratching. Prior to this I measured out my grain and gave about 2 feed scoops per day or 8 pounds. My girls are starting to look good weight wise but I worry about them over-eating... Will they?
