She is doing much better tonight!!! She has been in my shirt almost the whole day. I put her in the brooder while I collected eggs and shut up the gang. When I came back, I saw that she was standing momentarily and was lifting her head some. She was being picked on too much, so I did take her back out. She was able to momentarily stand in my hand.
Yes, Sally I do think I accidentally aspirated her. I had tried to avoid it, but apparently that's what happened.
Now I think that everything is OK, and she should be fine tomorrow.
