Wow, I am so very sorry, I can't imagine opening the box to find all those poor ones dead, I hope the next shipment goes better.
I don't think that the shipping was too long. I ordered mine to be delivered on March 31. They were hatched the 28th at 5 pm, shipped the 29th, and I picked them up on the 31st at 7:30 in the morning, all happy and healthy. They were shipped from McMurry to South East Texas.
Some of the black ones look my black australorps did.
