Hi Everyone, I have experienced this many times before my chickens perish.. And i want to know what it is. My hen, about 3 years old, isolates herself from the flock. She hides in the nesting box or in the bushes. I have just noticed this today. She is not eating or drinking, I am not sure what to do. I have thought about taking her to the vet, but i think there is nothing much they can do. Sometimes when she walks she lifts her foot up. I would appreciate any useful advice.
