MY wife says she has seen our 5 week old chicks sneeze. I'm not sure if it's a sneeze, but they do wipe their beaks afterwards. Also, bubbles out of the beaks? And finally, we go sit with them in the run throughout the day. At dusk they start crawling all over us (we don't pick them up, they hop in our laps) and start crying. Is this because it's getting dark out? We are bringing them inside around this time.
