I have a leghorn chicken that is about 8 months old. She has not laid an egg in about 12 days. She was laying very regular prior to that. She is not acting herself. She eats but very minimally. She seems to spend more time than the others just roosting. When we feed them meals worms, which she usually will fight with the others over, she will peck at a few and then walks away and let's the other four eat them. Her legs and beak look paler than normal. She is loosing weight. Brought her in to watch her better. Have not seen her popping yet, so I don't know if there is something wrong there. I have seen a few watery droppings around the yard. Thought she might be binding an egg. Gave her some liquid calcium, and soaked her in water for 20 minutes with no change. We tried to feel for an egg, but could not feel anything. Any ideas? I feel like she is just going to waste away.
