How long did you try that method? It will likely take some time for them to get used to having free choice feed and stabilize their intake. I free feed. What should only last me 9.5 days, lasts about 12. Yes, a lot of variables will play into individual results.I had read that chickens like when you have food constantly available for them, they feel more comfortable knowing that they can get food when they want. So, I put about a five gallon bucket worth of feed in their gravity feeder, which lasted about two days, they weren’t nearly as crazy the next morning, so that was a win. But after measuring the feed out, that was five days worth of feed that they went through in only two.
