I’ve tried two different methods and my quail preferred one while I liked the other ahahaha! Well, I guess technically three? When they were chicks they just had a small tray filled with food and it caused a horrible mess but the brooder was cleaned out twice a day so it wasn’t much of a problem. As adults, I tried a diy soda bottle feeder. I really liked this one as they couldn’t make much of a mess by kicking the food everywhere and they couldn’t stand and poop in it. However I noticed that they didn’t seem to like it and even though I had more than enough “access holes” per bird, they fought over feeding spots. Then I was gifted a picnic table bird feeder, for wild birds, and they much preferred this. They didn’t fight and I noticed they gained a few ounces even though I thought they were full grown. However, they definitely make more of a mess!
if you want something cheap and easy that keeps messed from happening, i’d recommend making one out of two soda bottles. There’s some pretty good videos on YouTube!
