Recently bought a little billy, whom I think had urinary issues to begin with. He peed all over me when I got him home and I noticed a small amount of swelling to his sheath. Anyway...fast forward two days later, he's at the vet. It's determined he has a urethra that has burst. Vet says from congenital deformation. Anyway! My point in all this is what should I feed my goats to prevent any urinary calculi?
