Complex shell brake

[helptoall]

Hi, ivr found a snail with a broken shell who has a big "hole" . when ive found him i saw all the mantel and lungs up to the heart. when ive found hin the mantel was"in place" under he "hole" and his foot and head came out from the opening of the shell. Now, a few hours later. his mentle is withdrown and the lip of the mentel is no longer near the lip of the shell.. its hard to explain but the snail is coming out from the hole instead of the normal opening. Im thinking what the best thing to do? first option is to let it be and just kipping him in a moist box with food and calcium, the secound is to brake all the shell pices that under the place where the mantel is ending, the third option is to try and fix the hole with eggshels.







here are some photo, please help and adise!

ive decided to brake the shell.. i did beacause he was in alot of pain,bubbling alot.. after i did he seems better, he is no longer bubbling and the mantle in a more suitible psoition. the last 2 days he did alot of shell growing, but in a very weired shape. its like a big growth ,that covered with a thin hard white layer. he still didnt eat at all..
