Recently I was having a problem with mites... so I dusted all the chickens, the coop, and nesting boxes with Diatomaceous Earth (DE). Before I realized I had a mite problem some of my RI reds were pulling some of their feathers out and/or getting pecked/feathers pulled by the others. The result was a red bare patch near the tail. The mites are gone; However, so are the feathers. The farmer next door suggested puting "Black Jack" tar on the bald spot(s). The theory is that it will keep the others from pecking on that spot once they get a taste of that tar and hiding the redness of the area. Personally, I believe that's a little drastic not to mention potentionally hazardous. I've been thinking about purchasing the "hair in a spray can" product sold by Ron Popeil. I figure that if it's safe for people, I naturally assume it should be relatively safe for chickens. Curious to hear others treatments for this issue.
