Sounds like you are getting a handle on treating your injured hen, great job your doing! Now don't forget to get your coop predator proof. Hens can lay close to the side of a coop sleeping next to chicken wire on the coop and a raccoon ect. can pull them thru the wire. Poor young innocent new hens don't know not to do this. Place her in an enclosed area in a laying box up off the ground away from the sides of a chicken wire coop might help. Good luck with your hen! Keep us posted!
