When I was a kid I killed some squirrels and the males were missing there (you know) and my dad said it was because the male squirrels did not want any competition so they chewed them off. Not sure but there were alot of squirrels around where we hunted.
My daddy taught me how to casterate a hog and said them boars would become barrows and turn out BIGGER and TASTERER than not casterated!!!!! So, when a mass crop is smaller is the nut-cracker BIGGER and TASTERER????? Signed: Just a Simple Preacher!!!!
The legend that adult squirrels castrate their young is in fact a "legend". When you harvest a squirrel that doesn't appear to have any testicles, it's a juvenile. Like most other mammals, it takes a while for them to drop. Adult squirrels retract their testicles into their abdominal cavity when it's not breeding season, giving them the appearence they have been castrated.
Kind of sad that the "legend" has to end within my family.
