Been down that road. Calf got kicked in the jaw horsing around with the cows a few years ago...well maybe 10 years ago now that I think of it. Swelled up really bad, assume it was at the very least a good fracture. Calf still managed to suck or drink to stay alive (I don't know how it did). Swelling went down and calf grew good and was a real good looking calf in the fall, but I knew I didn't want to chance it and sold it as a feeder.
Ended up that neighbor a couple miles away bought her and fed/pastured her until the next fall (long yearling). Before knowing this, I teased him about having one of those money-losing Herefords in his pastures of Char X and Angus cattle. Says to me, 'I think it's one of yours (thought he was trying to get a rise out of me) - but something's not right with it'. Heifer ate about enough to survive and that was about it. He told me that she never even came close to weighing up with the other yearlings and was surprised when I told him the story about her jaw. He would never had guessed when he bought her as she was lump-free.
I would take the money and run. Not every animal looks as good as a yearling as they do as a calf, and this one has the cards already against her.
