Iv'e always just scattered the food for adult chickens on the ground, in several places to reduce the competition & pecking, rather than use a feeder. So far, everything has been OK. With what I am reading here about feeders, I'm wondering if that I am setting myself up for problems, or if I should go with the "If it ain't broke, don't fix it." philosophy. A little more info that may help: I'm in northwestern AZ, not much rain, temps seldom lower than mid 20's and the chickens have free access to a run that gives them each about 100sq. ft. In the summer heat, I make sure the food is in the shade.
