I put my two chicks in the chicken coop with my four adult Isa Browns, but they were separated by a cage the hens wouldn't hurt the chicks. When I wasn't there, the chicks got out of it and the Isas attacked them. One is just fine, but my Leghorn is hurt. She is seven weeks old, a female, and these are her symptoms: Bloody neck Occasionally labored breathing. Sometimes a pinging sound is heard when she breathes. (but not all the time, sometimes she breathes normally) Green, watery poop. Smells horrible. Screwed up eye. Not drinking unless forced to. The hens pecked the neck and eye and now her eye is shaped funny and watering. Here is a picture. She is really quite beat up. Here is her neck. What should I do for her?
