My little RIR is getting too much attention from my Patridge Rock rooster. He's biting the heck out of her head while he's.....ya know, doing his thing. Her head is totally bald and now he's leaving puncture wounds. I've applied blue coat, but that doesn't seem to be helping too much. While at the feed store yesterday I happened to mention it to a lady working there. She said a customer of her's who is an old time farmer uses pine tar to prevent the rooster from biting the hens head. She's ordering more. Anyone use this with success?
