Will lockdown on day 19 to give the best chance for those that are closer to normal development a go without assistance in a second incubator. The rest I will assist as soon as the internal pipping is apparent.

It can take up to 12 hours from internal pip for a chick to pip externally. And that is completely normal.

It isn't until after that external pip that the blood vessels start to recede the yolk absorbs. Vessels need time to recede before you assist or you could kill the chick. Also keep in mind that hatching can take anywhere for 12 to 24 hours after that external pip. If a chick can breathe (cheeping), there is no rush to get it out right away. Just keep an eye on them. If you notice a chick pecking like crazy and getting nowhere after an hour or two, by all means help. But if a chick never manages to pip externally, odds are something was wrong with that chick in the first place.

I read that, but have had so many chicks die as a result of too much humidity related to my uncallibrated hygrometer and running the humidity at 60% or more from the start. I was tired of find dead in shell perfect chicks when I was not aware of the humidity error (I hadn't been checking air cell size, just for life on candling) and now I am better informed I am remediating the situation as best as I can on the misdirected (by the hygrometer). I didn't assist of the first few hatches and had many/most dead in shell without compensating for the little air cells.

I would not normally assist.. but under the situation I did and am very pleased that I have limited the losses.
