I am having a problem with a few things but mostly feeding. I have 4 different large feeders out there for 20 meat birds. My problem is that they eat out of these feeders until about half gone and then lay on them and of course poop on them. The feeders become dirty and humid and the rest of the feed goes to waste. Not to mention that some of these birds don't lay on the feeders but can't seem to get to the food because the rest are laying on the feeders. These birds are so dirty I can't believe it. My layers are right next to them and their run is clean as can be expected from a chicken but the meat birds run is all poop and food crumbles and stinks to the high heavens. I clean it every day as best I can. Am I doing something wrong? This is my first experience with cornish x. PLEASE HELP!!!
