I have been stalking now for a number of years, and the other day i saw a red stag with a big lump on the bottom of the jaw. I never shot this one but i have shot a few red deer in the past with the same lump. It is a large lump about the size of a tennis ball under its tounge and it is sollid chewed grass. I woundered if anyone could tell me what this is and if it is quit common. I have been told by one stalker it is a defect and the deer should be shot. and i have been told by another stalker it is whare they regurtitate there grass to chew the kud and is not a problem. If anyone could tell me the answer?
