I've been feeding the chicks with the little round metal feeders, they work fine except that the chicks like to jump on top and crap on them. Decided to try the red quart jar feeder, no room to perch on. I put a little food in the base and it worked like a champ. OK, fill the jar full with a good quart of food and head to work. Return home to find that they had billed the entire contents of the jar out onto the floor of the brooder. : (
