Do shipped eggs take longer to hatcg?

[EJBUSCHBACH]

Hello,
It's day 20 and about half of my non-shipped eggs have hatched and most the other half have pipped. However, none of my shipped eggs have pipped. I can see some moving, though. This is my first time getting shipped eggs and was wondering if they take longer to hatch. I had them upright for the majority of the incubation time so the air sacks could re-attach. i would have thought they would hatch sooner because they were closer to the heat source (I have a still air). I am wondering if they just are not as strong because they were turned less or they were overheated.
Should I put a safety crack in tomorrow if they still haven't piped, and they have internally piped?

I know it's still early, but they are just making me nervous because the others have all hatched or piped.

Thank you

You're only on day 20.

I'd wait for a few more days.

Do shipped eggs take longer to hatch? Not in my experience. Usually between day 20-24 or so, just like from my own flock.

Shipped eggs might take longer to hatch (like 6 hours) but it is probably related to egg age at incubation (time in transit), a slow hatch is more likely related to a cold incubator or cold spots in an incubator. Shipping can also damage eggs making them less likely to hatch. My first batch of shipped eggs hatched day 19/20 (quail) while the second was day 16/17, the difference was raising the incubator temp!

Different things can affect when an egg hatches. Heredity, humidity, how and how long they were stored before incubation begins, and just differences in individual eggs. Average incubating temperature is a big part of it but only a part. Some people say egg size can make a difference but when I experimented with my own eggs I did not see that.

Some things are in your control after you receive them. Some things are not in your control as they happen before you receive them. I would not consider "shipping" to be a factor but maybe something during that specific shipping had an effect.

I would not be surprised that different eggs from different sources hatch at different times even if they were handled the "same".
