My 14 month old chicken has been limping for over 3 weeks, It's not bumble foot I have soaked for 1-1/2 weeks in epsom salt, given her 1/2 baby aspirin keeping her in dog cage at night have a small pen on grass during the day near the other chickens, can't let her with flock they attack her. She is eating, drinking and laying a egg everyday. When it 1st started she would keep flexing toes on that foot, she now can put some pressure on the foot but still a bad limp any idea what it could be? Thanks
