My 2.5 year old hen had watery droppings for a while. Then she started to be more easy going with her companion and stopped bullying her. Then she started to lay pale coloured eggs. (They had always been brown up till then.) Finally she started drinking lots of water and became very tired. At this point I sadly destroyed her as I knew that she could not go on. Her companion, who was not so prolific a layer, has just started to be kind to her companions. She laid an almost white egg today. She looks tired. She is 3 years old. Have others seen this pattern with old, high production hens? They are ex-battery Warren hens. I am wondering if she is worn out or if anything can be done. She is still laying 4-5 eggs per week. She is on layers pellets and treats and free ranges around the garden. My other two young hens are not showing any similar symptoms.
