Last August, I hatched 3 chicks, and two grew up to be some of the friendliest roosters that I've ever had. Today, one of them inexplicably went lame. As I was getting ready to put his brother in for the evening, I noticed that he was limping to the point where he was hopping on his right leg, not using his left leg at all. Things that have been mostly ruled out: -Fracture from ankle and below. There is no sign of any broken bones on his calf or the portion of his leg not covered in feathers. -Paralysis in left leg. He can move it when he wants to and pull it up to stand like a flamingo, and my flock has no history of Marek's disease. -Foot wound. His foot was the first thing I checked. No sign of a wound. Possible possibilities. I don't know how to recognize these, nor do I know how common they are in less-than-one-year-old roosters who haven't been doing any particularly strenuous activities: -Hip or thigh fracture -Sprain -Strained muscle -Ligament damage -Dark magic If you know how to recognize symptoms to any of those, how I can tell, what I can do, and the recovery rate, I would greatly like to know. If it would help, here are a few things about his physiology and behavior: -Not quite as big as most standard breeds (he's a mutt), but definitely bigger than a bantam -Built light, but probably not underweight -Very easily handled. Submits freely to being held on his back, content when picked up -Enjoys flying. He likes perching in high places and is one of only 3 chickens I have had who has slept in a tree. -Somewhat responsive to "Louie" and "Who's a good boy" If there's anything I can do to figure out his ailment and/or help him heal, I would like to hear soon. I currently have him confined in a rabbit hutch with food and water and a hay bed he doesn't show much interest in sleeping on. Please reply if you have and advice on how I can help him, as I lack access to a veterinarian.
