One of my chickens had an injury to her middle claw on one of her feet. Her foot is now swollen & she does not want to walk on it. She spends most of the day sitting down & when she does try to walk she tries to put her foot down but is in obvious pain so either hops or limps a little lopsidely. I have read that the leg should heal itself but i am concerned about her general wellbeing as her crop is loosing it's redness. Is there anything i can give her to give her a boost? She is eating well. We've had bad weather ever since her injury occured which is not helping! Any help would be massively appreciated, she is an ex-battery hen & so had a rough life before we got her so i want to do everything i can to help her recover. Thank you.
