I ordered 25 from Whelp and got them within 5 days of order. One I think was damaged in the shipping, but was still alive on arrival. (It subsequently died, but I do not blame Whelp or the PO for that. Just bad luck I think.) It's neck was craned backwards and it kept trying to rest the top of it's head on it's own back, and then would wobble and fall over. I think it might have been broken. I contacted Welp a few days later (chicks came on Friday afternoon, so I called Welp Monday morning), and they credited me back for the one chick, even though they didn't have to do it.
My chicks arrived in amazing health and were vigorous right out of the box. They drank right away, and ate within hours. All survived (except the one with the messed up neck mentioned earlier). They will be 2 weeks old tomorrow and are growing at a nice pace. I'm amazed how quickly they put on their feathers.
I was so impressed with Whelp. If I ordered from a hatchery again, they would be my first choice. They always answer the phone on the first or second ring, you always get a person, and the one who answers the phone can always help you too.
Good luck with your chicks. I'm sure you will enjoy them!
