Hello all! New here. Had a hen get attacked by something, idk what, but it left piles of chicken feathers in a few spots. The hen managed to get to the barn but she is terrible weak and hasn't eaten or even drank anything. Hard deep breaths too. I don't want to cull her but will if its humane. Any advice? Thought about bringing her in the house and giving her some chicken smoothie (greens and egg) to see if that helps. Any thoughts or advice would be great.
