my 4 roos protect too and will flog a stranger.. when my grandkids come over i hug them tight and swat at the roos till they decide they are part of our family.. then they leave them alone.. i have to do this everytime they come over..2x a month..after they settle down i have the kids give them treats and tell them DO NOT RUN! if the kids run the roosters take off after them.. other wise they can sit on the ground and feed them with no problems. they can even go into the coop to get the eggs and into the run and are ignored by the roos...
