We need a lot more information in order to help.
Age of hen, when she last laid, pictures of abnormal droppings, any abdominal bloat, is crop function normal, any other symptoms, is she drinking, pictures of the bird sometimes help. How is she housed, fed, how many other birds, ages, all others normal, etc. The more you tell us, the more likely we can try to help.
Thank you for your response, yes i should have given more information at the time
Im devastated tbh, she past, i noticed on sunday another girl had the same colour poop and monday morning she was laid dead in her coop.
Something sedms to be ripping through my free range flock,
I have 15 girls of mixed breeds and a cockerel, all been totally happy n healthy, ive checked for mites both on them and in the coop,
I had noticed they havent been laying as many eggs recently,
There is a luttle feather loss in the coop
