Rooster wounded..!! need advice...

[Chiken lil]

my perfectly fine rooster (still in a very good state) was probably attacked by a cat and now has a patch of flesh showing on his neck!!! he does not show signs of pain and is still at pecking, running, etc. he even seems as if the only thing wrong with him is that a little of his hair/fur is missing. im really scared of what the result of this event could be.

Chickens won't show ill effects unless they are severely injured.
I would clean the wound well with hydrogen peroxide and put some neosporin on it.
If it's a gash then a stitch or 2 might help. If not it should heal ok.
If the other chickens start to peck at it which they often do you'll need to put some blu-kote on it.
