I know this thread is old but I thought it wouldn't hurt to update it. I went and picked up the colt in late December. Not long later he went in to an amazing vets office and I about fell over in complete shock when the vet checked him over before the surgery...He had absolutely NOTHING wrong with his uh..boy parts..
The vet said that one testicle was larger than the other and he figures that since the smaller testicle was hiding behind(vets words) the larger one the previous owner assumed he only had one. So in the end the total cost of his gelding,overnight stay.vaccinations and coggins was $326!
