Eggshell as source of calcium for snails

[snailkeeper21]

In this video, you can see snail eating eggshell that is not destroyed into small pieces nor the shell is turned into powder: www.youtube.com/watch?v=GYNqn0oDY7k

The snail that is shown, in the video, is African giant snail. My snails are garden snails. So, can i use eggshell as source of calcium for garden snails, or garden snails have weaker teeth than African giant snails?

If i turn the eggshell into small pieces, the pieces will be sharp. Can this hurt the snails once they swallow the pieces? If snails try to eat eggshell that is not turned into small pieces or powder, can this sawing the teeth of snails?

If snails see the eggshell for fist time, how will they know that the eggshell contains calcium?

Thanks.

Snails don't have teeth that chew or swallow whole chunks or pieces like mammals do - they have a radula that they use to scrape over the surface of their food.

There's no difference with the mouth/radula/digestive system of African snails compared to garden snails except that they're bigger.

Eggshell can be used for calcium if you don't have access to limestone flour or clean cuttlebone. Snails generally instinctively recognise calcium and are able to regulate their own intake of it, as needed.

Make sure not to regularly add calcium to their food or sprinkle it on top of their food, as this can cause over-intake of calcium that can lead to serious internal problems and even death over time. The calcium source should be provided separately to the food for the snails to eat when they choose.

Alright.
Thanks for the answer.
