This might not work quite yet, but I have this feeder. You don’t have to buy the feeder, the ports are available as well for a lower price and all you’d need is a bucket or a tub. No waste, mouse and pigeon proof and weather resistant as well. If you don’t want to buy the ports, it’s an idea you can implement if you’re good with DIY because it’s super simpleI have been looking but the ones that I am willing to try are out of my price range I would invest but I don't know if they will work they are like $60+ dollars and I don't know if its going to work thanks tho.
