We've had great luck this time around by putting a shoebox lid in the 3x4 brooder and sprinkling the food in there ( 20 chicks). Yes, it's starting to get some poo in it- we will empty it out in the yard- but the chicks are scratching as they will when grown and I don't see much being wasted. I had more being wasted when the shavings would be fluffed into the feeder and the chicks wouldn't see the feed.
