Isn't there some kind of powder to put on it, remember that from way back, wish I could remember what it was. Maybe you can google and research. Don't know if pine tar might work...It's a tough one. There's also a blue seal that I used when our rooster had a boo-boo on his leg and the girls were picking on him, it worked great. Got it through McMurray, but sure you can find it elsewhere. Hope Ping does okay, don't want those bugs to get way in, after all the poor thing has been through.
