Same concern here.
It's been found an 1.5-2 hours away from me in Dallas, TX. They were saying they found the flu in sparrows.
I had a huge flock of black birds this morning hanging out near my coop. My neighbors must think I'm nuts I went running chasing them yelling until they flown off.
I was talking to a farmer guy I know about this. He knows other farmers with birds. So they free range but they are all confining their flocks until this passes over.
I have mine contained all the time. They have their coop and a fenced yard with a fence overhead. I was thinking of putting tarps up so no droppings can get in from the wild birds.
Also they put Corid in the drinking water. I think is treats influenza in chickens, not absolutely sure though.
This gives a little information :

One sight said to wear disposable coveralls and throw away boot coverings. Let no other people enter your coop. Don't go to someone else's coops or handle other people's chickens.
They said a lot of water birds such as ducks carry the flu. We just stocked our pond with fish and guess what I had in my pond? 8 ducks!
Oye vey! Like we need something else to worry about.
Anyway hope this helps.
