Hello! One of my garden snails has suddenly fallen ill with what looks to be craw prolapse, when I look in the breathing hole it looks very full.. is it possible a snail can be pregnant and not lay the eggs, therefore they eventually hatch inside the shell? Any suggestions on how to help a snail with craw prolapse? I’ve seen very small information on sugar water and possibly trying to push it back in with a sterilised needle? Many thanks in advance!
