Ok, I have 4 BO hens, and they (to me ), go through an enormous amount of feed. I feed them a laying mash and they have access to a run that is filled with leaves and what not to scratch in and still they act like they haven't eaten in days. Not to mention all the grain that they spill out of the feeder that they completely ignore. How much should I be feeding them ,I want to keep the feeder full but there is at least 2 inches of grain covering the floor of the coop what am I doing wrong? I want them to eat but at the same time the waste seems to be toooooo much. Any ideas?
