I went out to feed and collect eggs about 1 week ago and found my black silkie hen sort of laying sort of to one side, head not held up and her feet sort of paddle or scratch at nothing from time to time. She will not move around and she will not eat unless I give it to her from a syringe. (I have raised wild infant birds so I am somewhat aware of how to do this and not drown her..yet it risky I know but she would certainly die if I didn't. She is happy to eat whatever I put in her mouth but I have to put it there). I also started her on antibiotic injections about 3 days ago. She is not sneezing or coughing, she does not have runny poop...No one else is sick in my coup. After I feed her she will often lay with her head up like a normal chicken but she'll grow tired after a few minutes and lay it back down again. She won;t stand at all..legs go straight out in front of her like she's putting on the breaks. Her feet work, she can feel them, her wings work....I can not figure out what is wrong with her! (Got thumped on the head maybe?). Anyone have any ideas what is wrong with her?
