Well first of all, we only see her maybe 2 times a yr, 2nd there are no other kids, in the house or that come over. I have a full acre of land that they free range on and they have an enclosed coop he can be kept in if need be. He is NOT aggressive with my husband or myself. This was the first time he did ANYTHING like this. I have talked to many other people that deal with chickens, and I have got the same response, they can be weird around little kids. Now that I know this, I will not let him out when she is around. I do not kill my pets over a situation I was not aware of. Since she went home, he is back to his same old self again.
