I have tried hatching eggs be for and realized later on that the thermometer on the incubator was off by 5 degrees!I usually hatch local eggs and I've only hatched shipped eggs once so I would definitely follow @jolenesdad's recommendations as he has quite a lot of experience. From my singular experience with shipped eggs, most of the air cells were detached upon arrival but I still had a fairly good hatch. I did have lower development from some of the eggs being completely scrambled from rough handling though. It's usually recommended to incubate them in an upright turner but since my most reliable incubator has a horizontal turner I took a chance with it and I don't feel it impacted the hatch rate at all and the horizontal turner is supposed to be more like incubation under a broody hen. So I don't think there is any harm in trying to incubate them under your broody hen in my personal opinion but I've also had good luck incubating my eggs and placing them under my hen at day 17-18 right before hatch. Good luck!
