Question on pipping timing

[sbusey]

Please forgive if this is asked often, I couldn't find a thread that covered it. I have 4 eggs that internally pipped yesterday and the first external pips in three of those today. My remaining 6 have not pipped at all. Two I think may be malpositioned as the body is not against the air cell. But as far as the others, is it normal for them to be lagging days behind the others? I have a DIY incubator, forced air, good steady temps and humidity.

Also, I am assuming to cater to the pipped ones on upping the humidity, is this correct?

Thanks all!

I am not a hatcher, but what temperature are you using? What's the humidity?

Are these call, Muscovy, other breed?

I think there can be quite a difference in hatching time, from what I have read.

Have you seen the Stickies on hatching waterfowl?

They are Cayuga and White Layer. They are at 100.5F and humidity in the 60's.

Not sure if I read the stickies, I will check.

This is one I was thinking of

I just had 2 hatch last Saturday, one on Sunday, and one on Monday. So they definitely can be days apart and still be fine!
