Hope he's not allergic to feathers.
We've all had to deal with dramatic sneezers. Usually, it's kids looking for attention, or a coworker laying the groundwork for an upcoming sick day. That's what's probably going on with this chicken, who drops a such a comically loud sneeze that it seems fake. As if he found himself inside the family kitchen and thought that a comically loud sneeze might get him out of whatever the cook had planned for him. It's the chicken equivalent of "Is anyone else hot? I don't feel well. Sorry about not shaking your hand, but I think I may be coming down with something. Trust me, you do not want any part of me in your soup. I'm just going to head back to the coop for some rest."
