Dead chick what to do?

I would take the birds back and get a refund. If his birds have a respiratory illness, they're all going to have it. Likely they don't show symptoms until they are under some stress, like moving. I'm betting when you merge them with your current flock, within a month you'll have sick birds in your old flock.

and I have to say, holy moley, I gotta truck some birds down to CA to sell! my prices seem high for my area, and I charge $20 for a laying pullet.

I agree - I would not want more of those birds on my property. OP, I hope it all turns out well for you and your flock.

They were separated from mine and all mine are fine. Mine roam free from my yard except the caged off area. No I didn't change shoes but I seriously think she was sick since I got her.

The seller agree to give me a replacement and that's fine with me. The three I got from him was a created cream legbar, an EE, and a cuckoo maran. He is more expensive than other seller around here. I got a Silkie and an ameraucana from another seller around the same age for $30. I honestly don't think I'll be going back to him again now after the replacement. But it is really nice of him to replace it for me. I'm glad...

Well, your birds have been exposed if they have been able to walk right up to the newbies enclosure and you have walked in both places with the same shoes.
That's why some folks quarantine, tho it's very hard to do it effectively.
