Hello BYC, I need some more advice please - it's not been a good week. She's 3 years old, and a excellent layer. She's very active, and she's pretty greedy when it comes to food! She's also the leader of the chickens. Now, this morning, she's lost her appetite, and whattles are no longer bright red. Her poo is liquidy white, and she just sits in a corner quietly now. We have another 7 hens and, so far, no others have these symptoms. Their coop is lined with fresh newspaper daily. What could be wrong with her?
