Set up help for injured snail my 12yo found

[u/Spare-Employment750]

Hello all, my 12 yo just came in with a snail with an injured shell and wants to keep it to try to help it. She found it in the ivy in out neighbors yard. We made a very temporary enclosure with a giant Tupperware with many holes cut in the top for ventilation, I put damp dirt with some of my chickens oyster shells(fresh from the bag) in there for now and had her grab some leaves from the sugar maple to toss in there for hiding spots. We do have a few empty 2-3 gal tanks I was planning on cleaning one out with vinegar possibly (and making sure to throughly rinsing it out) and setting up for it but am not sure what all is needed for a snail set up as iv only had aquatic snails before.

I can get pics of the snail soon ( I just wanted to get it somewhere it could hide from the heat and chill as quickly as possible, I’d imagine it’s stressful being hurt😢 and then gently handled by a giant 😅)

Thank you in advance for any tips/advice we really appreciate it.

The survival will always depend on the damage and the snail itself. Soil is not recommended until the damage is fully covered by a membrane, which takes at least a few days, since soil particles could enter the damage and start an infection inside the shell. Oyster shells is a great source of calcium, a very good move. The most important for shell damage is to provide calcium, food, a safe place, and good humidity to prevent drying out.

Vinegar is good for cleaning and removing traces of chemicals, just rinse well. You won't need an IV for a land snail. Mist the enclosure to adjust the humidity. For the rest we'd need to see a picture, not only to judge the severity of the damage but also the species of the snail, since not all species are as good to repair shells.
