I have a hen that I think is a white rock or rhode island white but the last couple days I was watching the chickens in the pen as I always do and she goes to the other side by herself while the other chickens are together on a log or something and she hasnt been active or real excited to see me for treats or anything and today I went up there and she was laying by the coop ladder half way off with her wing hanging on it and i picked her up and scratched her head and she closed her eyes then i put her on the ground and she stood for a second then she laid down and started to close her eyes and its sprinkling right now and she just laid there in the muddy dirt so i put her up in the nest box so she could be in a dry comfortable spot for now and I held the waterer in front of her and she didnt drink and i held food in front of her to and no eatin now I'm asking what can I do.....I need help FAST PLEASE!!!!!!!!!!
