My 4 month old heifer (Charolais) has developed a lump under her jaw. This lump has grown larger almost daily. It sits right between the V in her lower jaw and runs from her throat to the tip (kind of oblong). It's big enough that it droops about 2 inches. It feels somewhat medium hard. What could this be. It seems to be drawing her down, but she does eat and drink.
