Okay I've created 2 posts this week and never intended on creating 3 but one of my female quail's got attacked by a cat yesterday. I luckily saved her but she lost a lot of feathers on her neck which means now she has a bald neck. Fortunately she doesn't seem to have any injuries what-so-ever and she seemed fine, just a bit frightened. So I let her rest in her little pen with her other friend quail for the day. The next morning I went to get her out so she could play in the garden again and I noticed she was sitting in the corner; not moving. This was unusual so I grabbed her - she didn't run away which is not like her, she didn't even struggle to get out of my hands as she usually would do. I noticed by holding her up she was a bit light/weak. So I brought her inside and layed her on a towel in the living room. I've given her access to water, food and even brought her the other quail as company. All she does is stay in the corner, fluff up and sleep. I'm not sure what to do or what is wrong with her and I'm very worried, can anyone help? I know if I don't do anything now she will die as this has happened to one of my chicks before. Thanks.
