Hi I am a new chicken owner, I have a 10 month old Siapan hen. a couple weeks ago she developed a limp, which turned into complete lack of use in her legs. She can move them, and put weight on them, but if you let her go, she cannot hold herself up. she wobbles and just falls which ever direction is most heavy, she will flap her wings and try to catch herself, but fail and fall. Along with this leg/lack of motor skills issue, she has developed a swelling on the side of her face below her eye..it's only on one side. We have her secluded and giving her vitamins and an antibacterial, we did dose her with epsom salt for about 4 days, during that time she developed diarrhea. we halted the salt and her poop returned to normal, but she still isn't able to stand or walk... Has anyone ever had this happen? or have any clue what could be wrong? any and all help is appreciated.
