I was just talking with a co-worker who was interested in getting chickens herself, and she was somewhat suprised that I let my chickens free feed as opposed to rationing out how much they get. She had heard that chickens can overeat themselves to an unhealthy weight or even to death. I'm feeding the Layena crumbles and a toss or two or scratch (when it's not hot) to give them something to do. When I got started last spring it seemed like most of the feeder designs (both store bought and DIY) took a low-maintenance approach that would allow the chickens to eat whenever and however much they wanted. Thanks in advance for the input!
