New here and hitting the ground running so to speak. We butchered 3 chickens this afternoon. 2 Hens and 1 rooster. The first hen, I noticed, had spots on her liver that were greenish in color and oddly shaped. The spots weren't round or anything, just blotchey. Her stomach was filled with water. She never acted sick with the exception that her egg production was non existent. Her sister and the rooster had no other problems I noticed, but I handled all three birds. My concern is the first hen A) might have something contagious to the other birds, and B) the meat from her and the other would now be contaminated. What should we do? Should we worry? Is the meat safe?
