Unexplainable shell damage

[snuhan]

I have six juvenile Helix pomatias. I bought them back in October as babies. They came healthy and active. However, over the past month or so, I've noticed their shells getting more and more beaten up. I've since moved them into a larger tank with no hard objects. The cuttlebone was a bust, so I've been rubbing a little reptile calcium powder on most of their meals. They eat a rotation of zucchini, squash, broccoli, leafy greens, and the occasional cucumber. Despite all this, the injuries have gotten more and more severe. The tank is right by my bed, so I can hear whenever they fall- it's not often. I have no idea what's causing all the issues; I found one snail just today whose shell was frighteningly light, and one who suddenly has what I can only describe as a cleft in his shell. These snails are so young and sweet, and it's making me miserable not knowing where all these injuries are coming from. Any input is appreciated.
I should note too that I live in the US- to be honest, the legality of me just owning the snails is already questionable. I don't have as many resources available to me as some UK users might.

Hiya, I'm sorry about the snailies! I read somewhere that mixing calcium with the soil of helix snails helps as that's how they get calcium in the wild? It worked well for mine so far but that could be coincidence. What'd the humidity like, with my baby African land snails a lower humidity can cause bad shell damage.
If that's all fine it could just be their genetics, if they're all si lungs that could be likely. I they all seem otherwise healthy it shouldn't be too much of a problem xxx

Have you noticed them rasping on each other at all? Havee you got any pictures of the injuries?

I hadn't ever thought of that! I'll try it next time I clean their tank. I can't be certain on the humidity actually, but my room is a consistent 71-72F and I spray them three times a day. I don't think I'd call the tank particularly dry at any point in the day.
I have no idea how they were bred, though they came with an in-depth care sheet I know nothing about the seller. At the time I just felt fortunate to have even found them at all. 
They do sleep a lot but they all seem to be eating well. I assume they like to come out more at night. Thank you!

I personally haven't seen them rasping on each other. I think the strangest behavior I've seen was one noisily eating the film that had formed over him while he slept?
I can't get pictures at the moment but I'll add some tonight. The worst one looks as though his shell began to split, and one half went over the other. I hadn't even noticed it until just yesterday, and I check them multiple times a day.

I'm sorry we couldn't be more help! If it is genetics it doesn't mean bad snails necessarily, jut and shells. And they're obviously very well loved snails so I wouldn't worry too much xx
