I've wondered about the same thing, chickmania. There is just something strange about all of this happening to BIG operations where thousands of birds are being affected. The industry is being affected and with that there will be a rise in market prices. Egg prices are already high. What will they be in another 6 months if the producing population in these huge businesses with 10,000 plus birds continue to be affected?
The Lewis county infection has me nervous for our little flock. It is only a county or two away from where we are. BUT it is on the Mississippi River which I find interesting in that the potential for wild ducks, geese, etc to fly over or be around has to be higher due to the river being a natural habitat for wild birds.
Our birds do not free range and thier run is partially under our barn with only 60% out in open air. I have it fully netted with bird netting to keep the number of wild bird intrusions to a minimum. If I could figure out how to cover it with a tarp or plastic and not have it blow away I would. THe netting does keep the majority of wild birds out but I have had a pair of field sparrows that insist on nesting in our barn figure out how to slip into the run to grab a morsel or two of crumbles. I had to to laugh the other day when I saw the little female sparrow flying as fast as she could to get out of the run with a Buff Orpington pullet hot on her tail. That hen wasn't happy with the invader at all. I haven't seen the sparrows in the run for two days now so maybe the chickens made it clear that they weren't accepting visitors.
We don't have any large poultry operations near us as far as we know but yes, we are taking precautions. My husband even said, no new brds are to be brought into the flock. No exceptions and I think he is right. Hopefully the hot weather will hurry up and make an appearance and this will all be over till Fall Migration begins.
