I have been advised by a very knowledgeable friend to stay away from this pullets be the other chickens on the farm because they are most likely carriers of infectious Coryza and I will not risk my flock. It may seem harsh but my chickens come first. I will be taking steps and upping my bio security for my flock.

I've been trying to tell you that chicken diseases are nasty and you should avoid them if at all possible.
I am glad to hear this.
(The part about you NOT taking this bird home is music to my ears)
