Dad and I shot this one on the last day of the season in 1981. Nuts were dime sized. He was as fat as a finished steer. I have the year earlier sheds.
The base is not the same as sheds from a normal deer.
My daughter's first buck was this way. Testicles had descended, the scrotum looked underdeveloped to the point the kiddos asked if all Mule Deer's looked this way. We were told by a gentleman in town who had also taken a buck in velvet that they were afflicted with blue tongue. Whitetail were more susceptible to bluetongue, but it was known to make muleys sterile. I have never looked into this to be certain.
