I accidentally left the shade structure off of my silkie pen. When I came home, one of my black silkies was limp and drooling from the mouth. She cannot pick up her head. I took her inside to cool her down. She is breathing (I hear mucus in her nostrils). Does not want to drink water. Has anyone experienced this before? What can I do to help her. Will she be able to recover and move normally again? Thank you.
