Red flesh exposed
I'd start with a bottle of blu-kote. It contains an antiseptic and will color the entire area blue, which will keep the other chickens from pecking it.
edited to add: wear gloves, check wind direction, and be careful...it'll also make you blue for a really long time if you get it on you
