Ahaha, mauling the babies pre-birth. Hmmh, an improvement would be keeping the yukkuripot in a open-topped container so the babies cant run away and mess thing up. Maybe a transparent plastic box with an open top?
I love all these theoretical yukkuri-as-products type things. Seems believable that people would start trying to find uses for them. That these uses exceed the cruelty of most general livestock treatment is just an added bonus.
