Hello all. New here. I just had a 3 week old Straw Hite chick die. She lost her ability to get her legs under her, and started to open and close her mouth as if she was struggling to get air. We separated har and tried to nurse her back to health, but she did not recover. We tried surgery water, hobbling her legs, but she had no ability to get her legs under her. Has anyone never seen these symptoms before? Thanks in advance.
