That's okay, I had to look up Crazy Chick, too [though my search engine is ecosia.org, not google - they plant trees in deforested rain forest areas when you use their search engine, and yes, I try to plug it whenever I can, LOL]. I wonder if that is what my house hen had when she was little, then? She never had the classical wry neck so much as, when she was tiny, managing to go into a fit and tipping herself completely upside down, head over heels, and the Vitamin E and B Vitamin complex helped her tremendously! She is a bit mentally deficient (though for chickens, that does take some doing, I know, lol) and is nearly blind. As long as things aren't changed around her, she does fine. She hasn't had any fits of tipping over since she was about 12 weeks old (although she does still have the name Tipsy). She does recognize my voice, and if I only come up to her, she looks at me, and can't really recognize me unless I speak, but she does know where to look to find my face. So she's not completely blind, but she can't see enough to regularly manage to hit a treat or crumbles that I have in my hand. That takes her a bit to zero in on, to be able to find and eat. But, anyway, if it was Crazy Chick, and the definitions sound like it very well could have been, she does have an enjoyable life, though she could never actually be out in a coop and run, or especially not free-ranged. She's spoiled rotten, lol!
