I'm glad your child didn't get seriously hurt. Perhaps you might want to read up a bit more related in the flock management section before getting any additional chickens. One chicken will be lonely, as they are flock animals, so you need to consider what to do with your rooster now that he is the only one. The ratio of rooster to hen should be more than 1 to 1 as mentioned in a previous post, and unless you want baby chicks, you might want to just start out with a few hens. If you read up a bit around the forum, people suggest specific breeds that are more docile.
As far as kids and chickens. They can easily injure each other. I have 15 grandkids who come to see my girls, the youngest ones now are 4. I haven't used eye protection for my grandkids when they are around the chickens, but the ones who are younger than 10 or 12 definitely wear little gloves so their hands don't get pecked and pinched. We also have a bunch of "chicken shoes" (keeps the poop off their own shoes which their parents appreciate) in different sizes for visitors and make sure the kids wash their hands before and after touching the birds. I don't let any little ones under 7 pick up the birds -- I kind of treat it like picking up a baby - oops you could drop them and someone could get hurt. So the little kids sit either on the ground or on a chair and I put the chicken on their lap so they can pat them. I actually have only one chicken who really likes this, and you could carry her around until the cows come home and she'll just close her eyes in a contented way. the others just put up with it for a short time and then jump right down.
good luck.
