If this is the case where babies were dying before you even collected them at the post office then contact the sender & let them know the babies arrived either dead or almost.
I had it happen, and opening the box & SHOW the post office clerk the dead babies as a reference, and my clerks here want nothing to do with seeing the crnage that can be, in a chick shipment box.
But, at least it is documented and my shipper has refunded me.
the shipper (Ideal poultry) refunded me for the dead ones already. I still want to cry i'd rather have live chicks then getting my money back. I know it's not Ideals fault it's the post offices.
I will NOT have chicks shipped again knowing that they wont let me pick them up right when they come in.
