I like the philosophy of “treat for the treatable”. You can’t do much about brain trauma, which seems possible, but you can try vitamin supplements. If you are already trying that, then I’m not sure you can do much more… I hope you’ll update us as to how your keet does!I like to think that I would have noticed it before since I really like to watch them several times a day. I first noticed it after. It seems fine otherwise. It runs and jumps, eats and drinks. There is no lethargy, just shakes. None of the other chicks have this malady. I’m definately thinking trauma, but I can’t see anything outward. There is no swelling of the legs to indicate any ligament problems of the legs. It just baffles me at this point.
