What next

[ChristmasKathy]

We just bought 7 chickens from the flea market today.
I noticed the roo seems to be "coughing"? maybe?

Should I worm or treat the whole flock with something?

We live near jeffers

; anything they carry I can use?

You would probably get better chance of response if you post this in the EMERGENCY section.
That said, isolate the one with symptoms immediately.

Personally, if he's coughing and you have no illness in your flock, I would NOT treat him. He could be a carrier and mess up your flock for a very long time. Just cull him now, is my suggestion.
