I want to add a few chicks this spring, but I'm not sure what the risks are with avian flu going around. It has been reported in my state and county. My flock doesn't free range and is in an urban/suburban area with no ponds or waterfowl nearby, and I'm strict about biosecurity, so I'm not worried about my own chickens. I've read only about poultry farms housing adult birds as being affected. What are the risks to hatcheries? I'd get the new chicks as day olds from the local feed store (which is supplied by a hatchery). I want to use a broody to raise them, so quarantining them would toss that option out the window. Are day olds safe to add to my flock?
