About 3 weeks ago my White Leghorn (named Hop) hurt her leg, I've been trying to let it heal but its not, I have to get her out of the coop every morning and put her back in every evening, she used to be like the leader of the hens I have but now they've all excluded her. When she tries to walk her right foot(up to the end of the yellow) just stays limp and doesn't move, its also really cold compared to the other foot. she's only 4 months old so I don't want to put her to sleep but I don't want her to suffer. I let my chickens out of the pen about a hour before they go to bed, because I can't have free range chickens where I live, I bring out Hop and make sure she eats and I give her plenty of mealworms for protein, but nothing helping. I only have 6 hens and no roosters so I'd hate to loose one, what should I do?
