I guess I'm not the only one stumped.
Pigeon Fever crossed my mind, I cannot tell for the life of me if its coming from the sheath or just in front of it... I suppose if it was Pigeon Fever the abscess whole would be obvious to me however. My guess is its from his sheath. I just keep washing him up and he is feeling much, much better on day two of his Tucoprim powder however he is still "pussing" a lot.
No bute, just the antibiotic powder.
I cannot find anything online describing what an infection like this would look like, be caused by or what it could be. I have read anything from breeding takes place with in 14 days so that seems to be out. I am clueless!
