For anyone wondering, he did not take part in the superstition. He followed more of a route similar to horselovinguy's example. It was buried in the poop.. probably to keep the barn cats out of it.
KatieQ, it might have been due to the surrounding thunder but I didn't hear a crunch? I did really feel for the colt when they completely snipped off though. It was the last snip before the powder was applied and we moved onto the mare.
Incitatus, were you given a reason for the testis being put over the door?
As for the floating, the vet wouldn't let me really mess with the mare after she was drugged up and he had the specter thing in her mouth. He just wanted to get it done.. no worries though, my neighbor is extremely knowledgeable herself and was able to explain what was happening and why! Maybe next time. :)
