Here's a strange case: A 2-year-old bantam rooster with partial leg paralysis but no other overt symptoms. He can use the legs to walk-run, but if he stops he falls on his butt with his feet both pointing forward. His gait got stiffer, then he couldn't roost, he started falling over more. Now when cooped he sits with his feet in front. If he wants to drink or eat, he flops over on this side to reach the dishes. When put outdoors he will get up to move when he wants to sit in a patch of sunshine, but otherwise is not active. He has sensation in his feet and can move his toes. It's more like a weakness in his muscles, that he can't stand up or walk normally - he has to run forward and let the momentum keep him going. This has been observable for 2, almost 3 months. Ordinarily I'd say it was Marek's but the absence of the classic Marek's leg position (one pointed forward, the other pointing to the rear) has me stumped. Ideas?
