Killed this bird and and found this. I suspect he has been shot before possibly multiple times. Looks like infection of some sort there was actually a cavity in his breast full of what looked like feces. Found a pellet in the cavity also but it looked new and was the right diameter to be mine. Also looks like a pellet previously hit his beak. When I cut his legs off a large amount of yellow fluid ran out of both joints. He acted healthy before and when I shot him. I guess all we can do is speculate.
