Today I got home from work to find all but 2 of my chickens missing. We had 6 medium sized chicks and 3 full grown chickens, but all are gone. One chicken had both of its eyes closed shut from dried blood. The only injury on this chicken was maybe a few scratches on the face that scabbed over. I cleaned it off as best as I could while trying not to make it worse with a wet paper towel. The other chicken is in TERRIBLE condition. It's entire scalp was ripped up/tore off. I can't really describe it. It's hard to get a picture because it's hiding in a far back corner of the coop where I can't reach. I'm too afraid to try and treat the wound in case I made it worse. Both are hiding and not drinking or eating. I'm also concerned that the large head wound is infected. The top of the head has a large white glob? I'm not sure if it's pus or something else. These are my first chickens and there are no vets nearby who will treat chickens. I honestly have no idea what to do.
