Avian influenza 2021 in Chickens, Eggs and Hatching Posted December 4, 2021 Thanks both. Taking steps to limit infection in birds which might come into close contact with humans seems reasonable given the risk of human infection. I disagree that keeping the chickens under cover is no problem for them, though. Even with a pretty huge walk-in run, my chickens would still much rather be exploring the garden. Seeing them scratch around in wood chips all day seems pretty miserable to me. Fingers crossed it doesn’t last until April again.
