We got up this morning to find rhubarb (1 1/2 y old cinnamon queen hen) laying down. we let them into the run and she tried to hop on out. one of her feet is hurt. she can't walk on it at all. and it appears that one of her toenails is broken, possibly 2. Im not sure what happened. but how do I keep her from getting an infection and how do I get her well? she's not using the other foot at all. how do I know if it is brokeN?
