I was attacked by a banty rooster when I was 12.  Felt like a sledgehammer hitting my !shin, and I wasn't a crybaby!  My aunt took a large dog and a board into the henhouse with her...but my mischevious cousin locked me in barefoot to see if I'd panick.  I'll never forget his look of horror thru the window as he saw the roo attack me, poor kid.  If I had been a toddler, that roo would absolutely have gotten my face, maybe eyes.  I love all animals.  I don't kill ANYTHING, including insects, if it is unless it is suffering or I REALLY have to.  That said, I'd cull that rooster.  There are many sweeter roos being culled whom you could save, while keeping your child safe.  Good luck.
