Hi , your notice interested me because over a year ago now, I had a 11 yr old goat that developed an area that sounds like your ewe has. The vet aspirated some fluid ,which was bloody, serus fluid ,he thought she may have knocked herself but as she was a boss it seemed highly unlikely to me. We decided, in the interest of welfare as it seemed to be making her cough when she put her head down to eat , to drain it !! Big mistake , it drained then blood, fresh and a good quantity so it had to be dressed with a pressure bandage, stopped the bleed and was removed after a couple of days but the swelling reappeared.!! We then decided that she may have a growth somewhere that had infiltrated a blood vessel and that was the cause. I' m afraid the outcome was that the swelling got larger than ever and her cough a lot worse so she was euthanased on welfare grounds.
I am rented to say ,if she is well in all other aspects, leave well alone but have a chat with your get in case he has seen it before and is a simple job to clear up. Good Luck hope all's well long term
