This morning at 6:30am when I went out to water my chickens I was missing a chicken. We had just gotten a fresh 4 inches of snow, it was about 23 degrees out with a wind chill of 14. There was no sign of any other animal track in the snow. I grabbed a light and looked under the coop and there was my Speckled Sussex pullet (who just started laying), poor little thing was shivering and bleeding from her comb. After getting her out of run I brought her inside and noticed both of her eyes were swollen, her comb was also frozen and breathing was labored. After some a while of warming in up I was able to get her to drink and she ate some yogurt. Her breathing improved. I put the food and water in front of her and got her to drink on her own. I had to leave for work (was VERY late now) hoping she would be alive when I got home. When I got home her right eye was open but the left was still shut. She was drinking, eating and grooming herself. She even laid her 4th egg. Here is what I need help with, I plan to clean up her wound tomorrow morning and wondering what I can do if anything about her eye? How this all happened?? My theory is some time after 3:00am when my light on a timer turned out she was picked on by one of the older hens and she ran out of the coop to get away. I found a single pair of chicken tracks in the fresh snow going under the coop so it had to happen after 3:00am, I think she would have been dead if she was out there all night. After she ran under the coop she fell asleep because it was pitch dark outside. Not sure why she got picked on to the point of blood being drawn, she is the omega of the flock but they have been living together from the last 2 months and the pecking has gotten much less lately to the point where she eats with them when I feed them treats. It is possible the roo drew blood during mating and then the other hens just kept pecking. Either way I a little ticked at my flock for being so mean. If her other eye never heals I cant see how I can put her back with the 4 older girls without her being pecked and this happening again. I would hate to cull her. Any help and advice is much appreciated. Thanks all!
