So i have all my birds (chickens and ducks) in a chain link pen. I have a smaller metal cage like a rabbit cage w/three pullets in it. During the day i open the chain link gate so the birds can free range. Something went into the pen DURING THE DAY and opened the smaller cage killing two of my pullets. Injuring the other one. His eyes are swollen shut and bloody.....but ALIVE. I know the best thing to do would be to put him down. But it's just not in my nature. I can't do it is there anything i can do to help him? I can't even tell if the eyes are still there. I feel so bad. I feel he will either die of infection or starvation.
