How many days for shipped eggs?

[Old McRonald]

Do you typically see a longer incubation time on shipped eggs due to aging during shipping? I have a dozen silver laced orpingtons eggs I set late on May 25th, haven't seen any external pips and haven't candled for internal pips at this point but I was hoping to have seen progress at this point. I let them set for 24 hours after arrival before setting and heat/humidity have been right on throughout (had some bobwhite eggs just hatch from same bator on schedule). The eggs were said to be fresh and in transit for 3 days and very well packaged. Not nervous yet but, well, I want these to hatch!
Thanks,
Ron

Why would there be?
Not sure why an "aged" egg wouldn't hatch at same rate as fresh egg.
I have hens that collect and hatch their own so some are a day old and others are several days old. They hatch within 24 hours of each other.

See attached file bottom right hand corner it says "Eggs older than 7 days may require extra time to hatch." Moot point now anyway as 0 hatched but quail did so fertility or handling during shipping were probably the culprit.

You count day one at 24 hours after you put them in the incubator.
Shipped eggs don't take longer.
