I have a one year old hen who is acting lethargic, and just standing in one spot all fluffed up and won't eat or drink. She's been this way for a couple days now, she won't eat or drink. Her comb is still nice and bright red, and none of the rest of the flock seems sick in any way. I don't notice any difference in droppings in the coop to signal alarm, but I picked her up to check her out and she did have some mucous type of clear spray come out, in a very little amount. We went to our local Agway and they wouldnt sell us medicine for Cocci, because they said it sounded like egg bound and definitely not Cocci, and told us to use mineral oil on her vent. We did try that but still nothing, she just sits in the coop and stands by her nest. Any suggestions??? We tried to get her to eat a tums as well, but she wouldn't even nibble at it.
