Limping and droopy chicken

[tiffybear22]

I have a 7 month old pullet that for the last week has been limping and has a droopy wing. Her sister is doing great and started laying this week. She has grip in the bad leg and will stretch it out. We have checked her leg and nothing feels dislocated or broken. She is eating and drinking good. Her poo looks normal as well. Her balance is off. Any suggestions would be great.

Welcome to BYC. Do you know if she was vaccinated for Mareks disease? She may have an injury, but her symptoms could be those seen in Mareks which can cause weakness or paralysis in one or both legs or wings, and can also affect the neck. I would put some poultry vitamins into her water daily, and keep her in a small area or pen near her food and water. Make sure that she can reach it. Here is a little reading about Mareks disease:
