Broken Feather

This is the same goose I blipped on the 2nd but this time his broken feather is pretty obvious.  I have an almost uncontrollable urge to see if I can help him but despite the fact that I feed him bread (which you can see in his beak), he hisses at me if I get too close.  I'm hoping the broken feather isn't causing him any trouble.  I think there would be more trouble if I tried to intervene.
