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?
