Temperature drop during hatching

[Apomerantz]

Today is day 22 and I have already had a ton of hatches and a lot of pips, but I think my temperature just dropped down to about 90ish for maybe an hour! Did this probably shrink wrap my chicks? I guess I will have to wait and watch, but any tips would be great.

As far as I know, and someone much more experienced will give you a more detailed answer, but a drop in humidity shrink-wraps the chicks. The membranes dry and the chicks can't turn in the eggs to zip or get stuck to it when trying to force their way out. A temp drop at this stage shouldn't be so bad as a huge humidity drop for an extended length of time.

Right before the temperature drop I added some warm water, so I'm fairly sure the humidity stayed up there. Right now I will just keep an eye on them, if it seems like they aren't progressing I will have to step in and help.

I'd give them as long as you can keep your hands off them! If they are viable strong healthy chicks they will hatch just fine, if not, they could be better off without help.
