Why Benjy wouldn’t breed ...
This might not apply, but, a few years ago we had a neighbor who bragged about going out west and getting a hot bull to bring home and upgrade his beef herd.
He bought it as a calf and fed it all winter.
Turned it out with the cows and nothing happened.
Had the vet out.
Vet pointed out helpfully that nothign was happening because the bull had been castrated as a calf.The neighbor was sent the wrong calf.
Benjy might have been something like that.
Sounds reasonable, at that.
