I guess I'm thinking of the Rooster Booster brand of No Pik or something like that-- a similar product to the Blue Kote. It has a styptic, a winter-greeny smell, purple dye and a nasty taste.Blue Kote is a product that you smear on wonds and it is deep purple, so birds usually will not peck the otherwise red wound.
Rooster Booster is (was) originally a vitamin/supplement for fighting cocks, with alot of vits to help blood coagulation.
Alot of folks just use it as a supplement for all their fowl.
