I know MPC hatches at Meyers so I wouldn't worry. You might call at 3 eastern time which I believe is around actual hatch/ship time for them to get your tracking number. Do NOT put any faith in your tracking. A example is my chick's were hatched and shipped same place yours will be day before yesterday. I was really worried because of the long trip from ohio to California. On hatch day tracking said my chick's went to the Cleveland shipping hub I had no more tracking for 24 hours
I get a call that afternoon my chick's were here! ALL HEALTHY THANK GOD. I'm sure yours will be too. They take special care to ship with heat pack on time. Your chicks will be here in no time
