Thats always super sad to lose a new babe, so helpless so tiny.
What are your temps for the little ones? They are on paper towels right? Are you using a uvb light on them?
As far as what cecil said, are they in any way losing control of back legs, looking paralized in any way? Hunching their backs?
OR are they just seeming to become weak, and dying?
Also I don't know how you are giving the drops of water but I would not put it in the mouth, you can drown them, it can get ito the lungs if it is not put way in or off to the side towards back of mouth. I use a very very shallow plastic yogart lid, and fill the middle with water, like puddles and let them just walk through it and find it them selves so to speak, and they drink. You may have to put small amounts in the lid several times a day if it drys.
*Sometimes one is just not as strong as others and will die, I have had them hatch be fine for a few days and lose one. But if it starts to happen to more than one, then check everything three times over, otherwords, look at everything and see if theres something you may be missing. Just do the best ya can, I hope the others will get srtonger and do well , let us know.
