A friend's 10 month old Orpington rooster started stumbling and dragging his feet nearly a week ago. Within 3-4 days, he wasn't moving. He will eat and drink if we make it available to him, but he is laying on one side and will occasionally scoot around in a clockwise type fashion. He's alert, looks around, and will attempt to fight if you try to touch him. His legs and feet can move in a bicycling like motion, but he can't stand, and when I try to set him upright, he rolls to one side. At first we thought he'd been injured, because we found out a visitor had pushed him with a stick a couple weeks ago when the roo advanced. However, he doesn't show any other symptoms of injury. I wondered if he'd been bitten by a snake or spider, but again, he's mentally alert and aware, just unable to stand or move much. I honestly thought he'd die several days ago, so I'm surprised he's still functioning each day. Any ideas what disease/injury/illness we might be dealing with? Thank you!
