My 26 week old hen was doing great and all of a sudden her legs seem partially paralized. She has just started laying and has laid 3 eggs so far. I went to make sure they were all in the coop tonight and she was laying underneath it where they normally hang out. Her legs were out behind her and she couldnt get up. No trouble breathing, no mucus, good color and shes eating fine. Doesnt seem thirsty though. I only have 3 chickens right now and I hate to loose this sweet girl. She's a Gold Laced Wyandotte. Please help! And thanks!
