Hi. I have 2 3 year old warren chickens one is absolutely fine she is in the middle of a moult so is not laying. My concern is the other one she hasnt layed an egg for over 12 months which hasnt bothered me and she has been fine. The past 10 days or so she seems really lazy. She is sitting on the grass all the time she will come when encouraged for food and i do see her getting a drink when she can be bothered. They both slept on a wood beam in their pen and only use their little 'house' when it is cold. The wooden beam is about 2foot high. She just doesnt seem to be able to jump up anymore and waits to be put there or resorts to going in their house if we miss her waiting to be lifted. I have checked for injury and cant find any. Checked and dusted for mites but cant find anything, have used verm x for past few days stools are runny but i think that is down to verm x, nothing untoward in them though. Her feathers have been getting paler over the past few months and her comb in bent over and pale at the moment. Could it just be old age catching up with her. (We bought them at POL and are estimating they are both around the same age (3) could it be that she is older than we thought ??
