I have 26 chickens of assorted veriaty. I had been feeding them 5qts in the morning and 5 qts in the evening. They stopped laying and I got concerned it was a lack of feed. So, I converted a 5 gallon bucket into a gravity style feeder. I filled up that bucket Saturday and now it is Monday evening. I think that is probably a bit execsive. My birds are confined in a run most of the day only getting the last couple hours of daylight to forage. We have predators in the area and i dont like the birds out unless i am around. So how much should these birds be eating and what is the cheapest way i could go in terms of what feed i am buying?
