When to feed after cutting the umbilical cord?

[musicalKeyes]

So, I've got like, five minutes to type this out and it's a whole long story, but basically I started off with five good eggs and maternal incubation, couldn't keep humidity up for the life of me, and despite this mold started growing rampant in mom's tub. So I ended up deciding to put them in the incubator, which is a hovabator, but the damage was already done. Got the humidity nice and high but the eggs wouldn'y swell back up. Movement in all five until last week. A few days ago I cut them, and only two were still alive, the others had literally stuck to the sides of the eggs, poor things. I think because the space inside was so little, there wasn't enough of that egg goop to cushion them. One of the two left died yesterday in the egg. The last on had his head sticking out, but pulled it back in, and I was worried so I enlarged the hole and saw the umbilical cord wrapped all around him, so I couldn't even untangle him. I decided to cut it since I've done it before with chickens and seen it done on here. He's in a tub with wet paper towels now, I used cotton string to tie it off, although I had to do it twice he was tangled so bad. He now has a little sticking out before the string so he doesn't absorb the string too.
His head seems a little deformed, so I'm not sure if he'll even make it, but if he does, when should I feed him? His stomach is caved in and he didn't get any yolk, so should I feed him as soon as possible, or wait until he sheds like usual?
By the way, he's an adorable little spider. Four out of five of them were spiders, and the normal had his mom's really cool reduced pattern. I have some pictures I'll post later when I'm at my own computer, I pulled all of them out of the egg and three of them had wrapped cords. Next year I'm definitely planning this out better.
Anyways, advice?

You may have to assist feed before the first shed.

Thanks, that's what I figured. I guess I'll give him a day or so to rest and the give it a try.

I had to assist a baby normal I got. If you gonna assist, I would suggest trying to just place the head in the snakes mouth and set him down. No forcing it further in. Worked perfect for me. Mine could of spit it but just sat there, with the head in its mouth, for about 2 mins then started eating.

Good luck!!!

Yes I'd try to get some food in him to get his strength up. Just a pinky mouse. Very small. Push the head against the snakes mouth while holding the snake firmly behind the head (at the sides of the jaw) with your thumb and index finger and your other fingers curled around the body. It will open it's mouth with enough pressure. Try to get the head as far into it's mouth as possible and then quickly set it down in the tub and sit still. With some luck, it will begin swallowing. If it spits it out, try again but work the head of the mouse slightly deeper. If you can just hit the back of the snakes mouth it will trigger the swallow reflex once the snake is put down.

Keep it on damp paper towels at least until it sheds. It may take a few assist feeds to get it feeding. Just start small and keep us updated on it's progress.
