Another rookie question for the pros.
My little peckerheads are spilling more food than they're eating. [Before I continue, I want to note that the peckerheads I'm referring to are my chickens. That is the "term of endearment" I use to describe my chickens when they are being naughty. Because, literally, they are pecker heads.] Upon further study, I guess this nasty habit is called billing, and the birds use their bills to shovel their feed out on the floor. Bottom line is, I don't want to pay for food that the birds are going to waste. I want them to eat, not waste, the food.
My feeder is a 40 lb. galvanized steel feeder that is open on the top (where I pour in the feed) and has a round trough/pan on the bottom, where gravity allows the feed down. There ARE 3 different "levels" that I can set the gravity feed to. I have always had it set on the highest (most free-giving) of the levels, thinking the more food in the through, the easier all my chickens (of different sizes) will be able to get to it. The feeder is raised about 10-12 inches off the coop floor on concrete blocks.
Below is a picture of the type of feeder I have. What have y'all done to prevent food waste from "billing"?
