I have five chickens, one of each- Barred Rock, Red Star, Silver-laced Wyandotte, Cuckoo Maran and Columbian Wyandotte. They are in an 8x12 foot run with a 6x4 foot coop, plenty of room for five chickens, feed and water always available. Never had any problems before. Last night I noticed that the CW and SLW were picking on the BR, chasing her around and grabbing/biting her comb/neck area, STEPPING ON HER! When I picked her up and looked at her she had blood around her nose area, probably from the "wrestling". I set her back down and noticed her left wing was kinda droopy, then right away the two bullies were back at her, so I isolated her in a nice quiet dark room in a comfy dog crate with shavings, food and water. She seems okay (acting normal) except for the shut eye and wing. BTW it's her right eye and left wing so they are opposite sides of the body...and she has no signs of mites or any other pest problems. One eye is shut and the other looks kinda half closed. No draining, no yellow guck, no swelling, but I did notice a little bump above her eye up near the comb about the size of a BB. The wing could be hurt from the combat she has been enduring. They are SO MEAN! I hate that part of chickens! Anyone have any ideas what could be happening to my poor little BR (she's will be a year old around the 20th of this month). I am at work all day and don't get home until about 4:45. I checked on her this morning before I left and she looked very happy, just laying there looking at me with her one open eye - poor baby. I will take a pic and upload it when I get home, that may help. I want to help her in any way I can, I'm just not very experienced with a hurt chicken. I have read here about the antibiotics and treatments so I will be picking up something like Duramicyn or Tylan. Anyone have any ideas which would be better? Thank you for any advice you can give me, all you BYC'rs are GREAT !! I don't know what I would do without you all !
