I have an approximately 5 month old RIR cockerel that decided to squeeze himself through the rusty remains of a spring mattress. He hooked his wing and was stuck for awhile (a couple of hours, as we can best guess) even though he tried to continue to push himself through. He's injured, a cut right at the wing joint - flayed the skin open, but when we freed him he was running around and acting as if all was well. Would it be best to heal him before processing (he is a cull, regardless) or go ahead and process him? Do you believe the edibility of the meat was affected by the rusted mattress?
