My chicken is a 1.5 year old industrial meat hen. i know what you're thinking, they are supposed to die young but please dont make a judgement based on that, she is very strong. she's lived through a fox attack which removed half of the skin off her back, and had accumulated a limp from what i thought was that incident. Today, she was walking fine, and running to me like she normally does, and she fell over. She cannot stand up, and her right leg is completely limp. I dont know what to do. shes freaking out that she cant stand up, but i have her in a cage and she hasnt lost her appetite. please, I really need help. the vets are closed until the morning and i dont know what to do.
