Hi, I have a hen that just sits in the coop all day and doesn't come out unless you pick her up and put her outside, she then starts clucking like mad, she also does when you pick her up out of the nestbox. Also when you look at her, she puffs up all her feathers, starts clicking and puts her head down and rises her tail up. When I put her near the food she eats it quite agressively ( she bangs her head down into the pellets more than the others do) also, she doesn't eat or drink unless you make her and we bought her some yogurt, she loves it but we can't feed it her forever. When I held her, I noticed her eyes were starting to close and then open again, she blinks more frequently too. She has been like this for about the last month and I don't want her to die. She feels as if she lost some feathers underneath her especially around her crop area. I thought it was moulting at first but these symptoms must mean something else. What is wrong with her, please help.
