When my nephew was jumped, it took him from behind. I would think they would attack where they could. The eyes would have to be a small child and that would be ugly. Sorry you are paranoid, but I still have to say, free-range is good for some things, but there are drawbacks too. You risk your chickens lives and roos might attack under certain circumstances....such as too many roos, roo being too crowded, roo getting too old, someone causing a roo to be mean or other unexplained reasons. Penning them in, doesn't necessarily mean too much confinement or that they are all cooped up and deprived. I would imagine that I could fit about 1,000 chickens on the space I keep 66 birds. I say give them whatever you don't feel like taking the lawnmower to. But small children should not be mixing with these animals unsupervised. You are just asking for trouble, if you turn your back on it.
