I've a red sex link laying age hen. We had a predator attack and we aren't sure if she flew into a wall and injured herself or what. She had some blood from her nose and was unable to stand. We kept her safe and warm for the night and the next morning she was walking so we put her back with the flock. She now walks like a drunk and keeps her head tucked into her body. She sometimes has to use her wings to balance her. Will this go away or is this permanent? Is she hurting do you think? I'm wondering if we are going to have to cull her or if she'll be fine like this. Thanks.
