So started off last Friday with losing a newborn buckeye and yesterday I found the elder statesman of the barn (really big lavender buff) hiding in between 2 bales of hay. Hesitant but not hostile to bring out. There was blood and scabing on the front of his chest and he wouldn't eat or drink. I thought he was headed to the big coop in the sky, he is 8 or 9 yrs. Made it through the night but still burying himself in the bales. Son found a huge (4in long 3/4in wide) bruse on his right side from below his wing up to his neck! No blood, no heat, can't tell about swelling. I have him isolated with the chicken who stays close to him, but seems in a lot of pain/discomfort. Anything I can give him for it?
