I honestly have no idea what got him. His only visible injurys are to his comb but i think he has something internal going on. He's just sitting out in my isolation coop 830 my dog lost his mind amd would not stop barking until i walked with him around the whole yard. All the girls were down in one corner obviously scared. They relaxed when they saw me and the dog. after i found my cochin roo injured at 1 i did a head count and found my wyandotte roo with blood on him. He had blood on his chest and legs but no injuries. I can't decide between a predator or roo fight. The cochin is head roo and a year older than the other. He far outweighs the young one and the other runs away whenever he comes near. I can't see them fighting without the cochin having caused some injury to the other. I know i have a possum back there. He got one of my meat chickens a few months ago and i never was able to catch him. i don't quite know how to proceed now.
