That's kind of a tough one, did they arrive warm or 50 degrees?
I am too inexperienced to answer but you do need to let them settle for awhile
Do some searches in the forums. You will find an answer.
All the eggs my DH and I purchased we let set for at least 8 hours,sometime
A bit more. Large end up turned clockwise twice a day if they waited for others
To arrive at as close to 65 as poss. Our weather was always cold here in Oregon
When the eggs arrived so we didn't have to wonder about cooling then down then
Heating them back up. Good luck
