Update: I sat and watched them for a little while longer and she was interested in food, she ate pellets and some scratch. She seemed to be acting pretty normal aside from being slightly less active than usual (it is hard to tell just yet what is "normal" since they are so new to us). They are all 8 week old pullets. I have heard some other random sneezing but nothing else that worried me. I think I am going to see how they are doing tomorrow morning and if she has not improved I will isolate her. I just don't want to pile on more trauma prematurely.
Any other info is welcome.
Mustardtiger- you got yours from empire acres, right? we picked some up this weekend from there too ( two barred rocks, which are about 6 weeks old and an easter egger and 2 buff orpingtons that are 8 weeks old) I noticed that our new easter egger had a bit of a sneeze going on too, and it was a little yuckier sounding than my other chicks sneezes....I did notice though, they were in wood shavings at the farm, and I have hay in my coop, so maybe that had a little to do with it- today though I have not noticed her sneeze once- I have not been around as much, but in the 15 min. I was out there tonight, no sneezing!
SOmething that is sort of funny- I suppose my original flock is quite spoiled...and fat! they are 6 weeks old, and are almost as big as the 8 week olds we just got..and the 6 week old barred rocks are quite small in comparison.
