My beloved Easter Egger, Beatrice, has been limping for about a week. It seems like it gets better but then it gets worse again. She is eating, drinking, and laying like normal. She does sit down once in a while and is the last one out of the coop(used to be the dominate one). I checked her feet and nothing looks to be visibly wrong. Is there anything I can do and does anyone know what's wrong with her? Pulled muscle? Thanks!
