Im just gonna say i dont think toddlers and chickens in general mix even a hen can peck out a eye within split second. you get down on their level and you will find that they find eyes very interesting as they shimmer in the light and are attracted to it. So if you have little kids you really shouldnt be free ranging chickens, they should be in a run. Which then if you have a mean rooster it really shouldn't matter cause they will be separated by a fence.
