Cknidy, I have a chicken that seems to choke occasionally. It happened first when she was a pullet. She made a loud squeaky/coughing type noise, and I was sure she has about to choke to death. My chickens freak out if I pick them up, and since I wasn't really sure how to help, I just watched her and she recovered on her own. It still happens occasionally, -always this hen. The last time she sounded like she had asthma, just gasping for air, and as usual, I was sure she was about to drop dead. A few minutes later she was fine. She does tend to gorge on any snacks that appear. She could be the poster child for the eating expression "I really inhaled that".
