This is the stuff you want. It is marketed as a hoof repair product (put out by a company called Horse Health Products), but works on chickens, too. I have to tell you that pine tar is not my first choice because there are better products on the market Pine tar is such a disaster to work with that I generally try not to use it. It works to stop picking, but it needs to be reapplied often and it is a stinky, sticky, goopy mess that gets all over everything. Yuck!
If you are having picking problems, I'd recommend the pinless peepers. They are the most effective tool on the market to stop this behavior. Once they are applied they rarely need to be reapplied, so it is a one-shot-deal. Much easier than messing around with topical stuff.
I have a product that seems to work pretty good. You need to reapply every few days, as it wears off, until the pecked spot is healed. It is called "Peck-No-More", made by Rooster Booster brand, and I bought it at Jax in Colorado. I believe Murdoch's also has it. Probably any place that sells chicken feed, etc.
I've had chicken saddles and sewn on tail wraps to prevent the pecking...but they are still finding ways to peck each other. Right now my poor rooster is wearing a sort of a skirt so his pecked bottom can be grow feathers...any ideas?
do pinless peepers hurt the chickens?
