We have a nearly two-year-old Blue-Laced Red Wyandotte hen who has been very lethargic for several days now. She is not interested in eating, and she drinks very little. Aside from the lethargy and lack of interest in food and water, she appears healthy and sound. I did check her vent and it seems dryer than usual. She is pooping, but small poops (probably from lack of food and water). The poops look normal, containing both urates and feces. I tried feeling her abdomen to see if I could "feel" an egg or other mass, and then I felt the abdomens of two other hens for comparison. I think I felt more "mass" in this girl's tummy, but it could very well be my imagination. I was looking for signs of being egg bound. We removed her from the rest of the flock two days ago and put her in our "hospital", which is a large cage inside in a warm, very dark bedroom. We have found in the past that full-time rest (in the dark), along with warmth, seems to have a very positive affect on chickens who seem ill or are healing from an injury. We do bring her out every four hours or so into a bright room to offer food and water and to observe her behavior. (We do have food and water in the cage, too, but as you probably know, chickens rarely eat or drink in the dark.) Usually, we seen improvement fairly rapidly. However, there has been no significant change in two days. Do any of you have ideas of what may be wrong and suggestions for what to do? If she is egg bound, I have heard that putting the hen in a sink of warm water (for I can't remember how long) can sometimes relax them enough that they will release the bound egg. Two more notes that may or may not be clues: (1) A few days ago, someone laid a huge egg--104 grams--with a double yolk. We don't know if it was this girl or not. (2) This girl prolapsed a year or so ago but healed completely and has had no problems since.
