My chickens have gotten into the habit of picking at each other out of what appears to be a mix of boredom, dominance, and an ungentlemanly rooster who has since been removed. So, after looking and looking, I finally got my hands on some pine tar. My question is... how do I apply it? Do I just slather it on the bare patches, or on all the feathers? Is it okay to put on the throat, where my EE has had her beard peck clean off? Also, is it okay to eat the eggs from them?
