So our snake gave birth on August 9th, we have looked up boatloads of care guides on them. They are feeding on fresh farm raised tilapia that we buy from the grocery store with no additives, no nothing, just straight up fish. I'm only having 5-6 babies out of previously 16 eating food. I spend about 2 hours with them each day, doing everything I can to get them to eat. Some just aren't interested, some gobble it down as soon as they see it. I have read that some people have had troubles getting their little ones to eat, so I thought nothing of it, as it hasn't quite been 3 weeks yet. I have been dusting their fish with reptical calcium, but more importantly I just want them to eat.

I went to feed them today, and there was an overturned baby, crushed, biting his side, floppy and cold, already dead. Thing is, this is a baby that hadn't eaten food. And just a few minutes ago, there was a baby that suddenly started flailing and spazzing around, his sides crushing in. I'm pretty sure he's dead now. Yet another baby that hasn't eaten. I'm not quite sure what's going on. I had at first thought that the first baby was possibly defective, as he didn't respond quite like the other snakes (allowing me to just pick him up and move him around without any reaction), but this snake was perfectly fine other than the fact he hadn't eaten.

They are on papertowel bedding, their water is fresh filtered water that sits out for a while before I give it to them, in a well thoroughly cleaned pickle jar lid. (Didn't clean it with soap or bleach, just ran hot water over it for a long time.) They are all staying hydrated, I keep moist papertowels in their hides which were toilet paper tubes, but I took those out temporarily to find out the cause of their random crushing.

I would appreciate any and all help I can get, I can't find any info about this, and I'm starting to get worried about them ._. (More so than when they were born, lol. stressful.)
Thanks in advance.
