I have a 9 month old chicken that I just noticed today was laying in the dirt under the chicken coop and not moving. She was trying to get up but her legs were just limp and so she was stuck there. I picked her up and put her in a box in our laundry room with some food and water thinking that she might be cold. She would try to lift her head up but would just bob back down into food or into the pine shavings. She ended up eating alot but not really drinking much water. She is alert and makes noises when I pet her but she cannot stand. I try to hold her in an upright position and she just falls back down if I don't hold her up. It's almost like her feet and legs are dead. She has been laying in the same position for most of the day. I don't know what is wrong with her.
If anyone has any advice or suggestions as to what may be the cause and if there is anything I can do for her I would greatly appreciate it.
