Review on 🐦 RentACoop Dual-Port Feeder: Ideal for Chicks, Quail, Pigeons, and Bantam Chickens (2 Small and 2 Large Feed Ports) by Becky Haferkamp

They work great. Food does not spill or spoil. I used an empty cat litter bucket because of the straight sides and high height-to-base ratio. A taller container is better than a wider one because the birds have access to all of the feed and I don't have to keep repotting it. I put both the small and large ports in the same container so the birds can decide when to switch to the larger size. I was worried I wouldn't notice if they outgrew the smaller size, but this solution worked great. And the nice thing is that these cat litter buckets are free to almost anyone with cats, so if they break, I can replace them. I have it in the shade so it should last for years.
