The threat of AI in the North this time of year is probably slim since the water fowl have migrated South (our neck of the woods in SoCA). However benign AI is to humans my concern is for our flock and how deadly it is to them. Is it only water fowl that's spreading AI or has it been found to be traveling via Hawks, Sparrows, Finches, Doves, Phoebes, Hummies, etc, as well? There is absolutely no way to completely net our property from those little pests or the visiting Cooper's Hawks. We use treadle feeders for the chickens and nipple waterers to eliminate the wild birds from mooching the chicken's food but the pesky little wild bird species just keep coming into the yard and dropping their parasitic little poops everywhere! The chickens will chase off the timid Doves but Sparrows are the worst aggressors of all our visiting wildlife birds. Eliminating available chicken feed source has lowered frequent visits but the darn things still come in swarms. They're like locusts!
It can be in any bird. As an example one of the AI positive birds was a falcon.
