ok been letting chickens out for half days for free ranging. today after letting the chickens out my wife found one in the coop that she thought was dead. well she was basically lifeless and looked very sick. i have put some poly-vi-sol in her mouth with a dropper. Inside her mouth is what would only be described as a clear sticky slime. The poly-vi-sol didnt really go down and she made a gurgle sound. what to be done. i have felt along her neck but dont really know what im feeling for. it feels "normal"
