File a claim with the post office and email the the business you got them from and tell them whats going on they will probably send you more
All of the sellers I've dealt with have said "Sorry. That sometimes happens with shipped eggs". I've had one to offer to give me a discount whenever the USPS starts to improve and I want to buy eggs from her again. I am working with a couple of folks that seem to be so helpful and encouraging. They've both mentioned that they will work with me if I have problems with USPS. This is out of 7 or 9 sellers. One mentioned to me that she's had an increase in folks try to take advantage of her since the COVID-19 stimulus checks (?) were issued. It's just a difficult time for so many right now. I also encourage this, but it's on USPS, so it can go either way. It's best if you leave feedback on your interaction with the seller and the way your eggs were packed (not hatch rates). Even though I have had mostly horrible experiences, it's on USPS. I feel for the sellers and the buyers because both ends are losing, sadly. Just today I was tracking a dozen eggs that were at my local distribution center (only ONE stop away) only to see them move to the WRONG post office. So instead of getting them tomorrow, I will probably not get them until next week.
@Lilalienangel
Have you received your other eggs yet?
