I had a red tail fly under the hen house (which was mostly protected) grab the largest bird and try to eat her right there. When my husband managed to run at them, the hawk couldn't lift the hen to make a get-a-way. This happened to my silkie bantam yesterday. She is alive, but was stunned at the time. This morning it her right eye is so swollen that it appears it might be missing. It is oozing a clear fluid now. I'm not sure how to treat her. She is eating and drinking. Is there something I should give her to avoid infection?
