Hi, one of my chickens recently got frozen feet. She wasn't sleeping on the roost so her feet got frozen. I took her inside and ran water over her feet, making it progressively warmer. I then put some shavings in a box with food and water and put a heat lamp over her. She has been there for 2 days now, and she has trouble moving around. Her toes are all still intact, but she doesn't appear to be able to move them. Are her nerves/muscles damaged so much that she won't be able to move her toes again? All comments and tips are welcome.
