My black sex link hen (4 years old) has had a pendulous crop for a couple of years now. She seems fine otherwise. Her crop has been getting larger lately, making me think it's not just her crop but possibly a mass in there. Now she has a weird hitch in her gait. It started with one leg, she would pick it up twice before taking a step. Now she does it with both legs. She does a weird bicycle thing with her foot every step, just one hitch per step. Sometimes she walks normally, but she mostly does this. It seems neurological to me, I can't find anything amiss with her legs otherwise. She is bright, alert, eating, drinking and roosting ok, and is in good weight. Her eyes are a normal color. She keeps up with her girlfriends when they're out in the yard. I plan to put her down if any of this changes and I feel she's not feeling right. Has anyone had their chicken do this weird step thing? I tried to get her on video, but of course, she wouldn't do it for the camera.
