A Buck whose balls didn't drop

True

Cactus buck

True. And they will continue to grow as much as his body can support them.

True, he is a cryptorchid, if I remember from animal reproduction class he doesn't lose velvet, shed antlers, neck won't swell and is sterile. I think the elevated temperature of his nuts results in testosterone levels that start diminished and never rise in the fall like a normal bucks. So, he never goes through the rut cycle.
