I've gotten 2 different shipments from Meyer in Ohio. One in March and one in August. March delivery I had 15 chicks and one died in transit. It was very cold. The August shipment I had 6 delivered and 1 died. So really you just never know. If it is a reputable hatchery then they know what they are doing and will put heat packs in there. Also, it took 2 days for the chicks to arrive even though I am in PA and they are in Ohio. My PO is very slow. They would prob make it to you in 1 or 2 days max. I love Meyer for their chicks and customer service. I also recommend the vaccines that are offered. I wouldn't mess with doing it myself. Just have them take care of it if offered.
Good luck!
