Currently, I'm commingling goats and sheep with chickens. All are free-range with in an 8-acre pasture. Free-range because animals limiting where they go so far, rather than the fence limiting movement. Problem that has become evident is where the goats are consuming feed left out for chickens. Scattering feed over ground helps some although the sheep and goats get more than I want them to get. I have been trying to place feeders on of various existing structures although goats can get into those used so far by standing on hind legs. Shortly I will be using a bird feeder where food is better than 6 feet up. Will be fun making so if holds enough feed for the chickens.
