I am not here to upset anyone, but I advocate for the chickens. They all look like they have very deep wounds and are more than likely in SERIOUS pain.
I suggest humanely euthanizing them. If this was a single chicken, a favorite pet perhaps, I could understand MAYBE trying to save it's life. With the shape ALL of these chickens are in, it would be better off for everyone involved to put them down.
Sadly I have to agree. These are serious wounds that will take a very long time to heal and be very painful likely the whole life of the bird.
