I have chicks in my outdoor brooder that will be three weeks old tomorrow ( monday ) and have had two other batches in there and had the same problem with them. I have tried the little auto feeders with the holes cut all the way around the bottom and now have graduated to the 7 lb hanging feeder and I am still having too much feed waste through the bottom of the brooder. I cant seem to get a handle on this. Any suggestions on another kind of feeder that is less wasteful? I get probably 1 1/2 pound of waste per 7 lb of feed. my brooder has a wire bottom so all the feed just falls through the bottom and I can see the waste and it just kills my soul to see all that feed go to waste.
