NEW EMERGENCY. We noticed two days ago that one of our hens was not moving well. And she can't jump up into the coop opening. She'll stand for a short time, but then sit back down. We gave warm bath last night. Cleaned poop off her bottom. We checked for egg stuck, and didn't feel anything. Not sure if it's the same bird, but we had a chick who always had to have poop removed from the vent. We've had sudden weather change, but others seem unaffected. Help! We feed organic and will be so sad to lose her. 9months old. Not sure of breed. Brown. Common.
