A couple days ago a fox came lurking around and my husband caught it before it could snag a chicken. However it did spook them and they all flew up and away from it. My silkie female was one that was spooked. Now the fix NEVER touched her and she walked back to the coop on her own. The next day her leg was lame. I've checked her leg and there is no slipped tendon, no swelling at all, and no heat. Her leg is perfect visually and to the touch. What could be wrong? She is active and alert but she has stopped eating and is thin. I've bought some meal worms and expensive vitamin enriched chicken feed. I've also put probiotics in her water. With her nit being able to stand her good leg is being comprimised. Any advice? Please spare me the culling her speach because I really like her and that will be a last resort.
