baby snails dying, what can I do? 

That Basket is very airy, the Soil is very rough , maybe you have too much moisture.

Change the soil to a new one,let it not be too strong or water logged,just slightly moist.Through away those decaying leaves,get plantain or coco leave for mulching.Add fresh leaves,or other food then cover them with the mulching materials.Dont over crowd them,and also provide enough calcium for them.Blessings of the lord rest upon you to succeed.

I need help concerning this too

As you lifted the leaves, I saw a soldier ant making it's way down through one of the cracks. They kill adult snails to talk about baby snails. Treat the soil and make sure ants can't get in there

They are over crowded.

I don’t know much but I think the baby snails are overcrowded in the basket, and also I’m sure the environment is not conducive for them cos I could see ants in there which is very dangerous to them. I also think it’s not ok to cover them with their feed cos they’re still babies and might not have much strength to climb up from beneath the food and that could also cause them to die

The soil is hard for the babies. The leaves are rotten without nutrients. Change the leaves constantly with fresh ones.

You need good management, use good soil and use plantain leave then always watered them every day, but don’t let the water be too much there, good soil, plantain leave, then Good watering 💯🙄

I am not experienced but I think the Housing is Not correct

You are Mentor, your Posts motivated me. I think you have been very busy of later so you missed some Points.

Too much over over crouded.Treat you soil and reduce their numbers.

First the covering of the leave is too many and there is no ventilation to the baby snails second ly the pen is too dry.
