I can't help with getting new eggs, but I may be able to offer some suggestions with your current batch! It'll bump this thread up also.
what day are your current eggs on, and how are they set in the incubator?
Most people stand the eggs up point end down if they have detached air cells. Some people also don't turn shipped eggs the first days, so I would say it'd be best to turn them less frequently for the first couple days.
Also did you let the eggs rest point end down at room temp for 12-24 hours before putting them in the incubator?
Sadly shipped eggs often have low hatch rates I believe, especially if they have had a rough transit.
But I hope for the best for you! Hopefully you'll get some babies!
