I made my own treadle feeder out of a small step on plastic rubbish can since I didn’t want to spend a lot of money or build one from scrap wood. I just attached a flat piece of wood to the pedal (drilled a hole and attached with a screw) so they would have a bigger step pad. I made the inner can smaller by cutting it and making a new floor that the girls can reach. The lid is made of plastic so if comes down, it won’t hurt them, but heavy enough to stay down and keep out rats and wild birds. Total cost $15
