You know, when we were little, come to think of it I do remember those two white leghorn roos we had as Easter chicks chasing us once in a while. We used to think it was hilarious, though, when they would run at us and spur us; never hurt much; sorta like a basketball with small spikes, hitting your leg. They used to chase the paper boy, too and he would run around the house to get away from them. Comes back to the same thing; I think it depends on the individual and also how much you handle and pamper your boys; maybe a little to do with the breed. We have had a lot of roosters, and only had one who would chase us; he was a pain; a Barred Cochin, brother to the one we have now. We had to carry a broom around him; or Whitey roo would protect me from him. The Barred Cochin we have now (his brother) is a sweetie; never offered to hurt anyone, and very calm and even tempered.
