We have had allot of trouble keeping our dog away from the chickens. She has already killed 2. Well yesterday she attacked one of our golden comets. We managed to get her off of the chicken, but tonight my brother noticed the chicken couldn't get onto the roost. Upon closer inspection we saw a wound somewhere (I don't know all the details. I myself haven't seen the chicken), and were wondering what are some good oils or first aid we can give her? Also, it is 57 degrees outside, and supposed to get to 52 tonight. We have an un-insulated coop with 12 other chickens. Will she be warm enough, and do we need to confine her? Some of the other chickens are pretty mean, and i'm worried they might beat up on her. Thank you!!!!! UPDATE!: Thanks for the quick responses! Ok, I got more info: The wound is pretty much directly on her back, and is pretty big. It looks like a beef roast uncooked. We would isolate her, but we can't find our dog carrier (which we usually put the chickens in), our brooder is a no-no for many reasons, and we just can't find anything to put her in. We washed the wound and sprayed "lava-derm" on it ( a mix of lavender and aloe-vera). That should hopefully help.
