All animals capable of harm cannot be trusted completely. Especially with small children who cannot defend themselves as well. The reason we trust our hens is not because they are all nice - we all know this is not true. I have a barred rock who pecks at anyone who tries to touch her - but, the peck isn't harmful. We can trust hens because they are not capable of doing any significant harm.My daughters favorite rooster had to be culled. We tried working with him for several weeks nothing worked. He “danced” and charged my 2 yr old and then bit my four years old and didn’t want to let go. Now she has a scar on her hand. It’s not worth it. She cared for that cockerel and was always gentle and kind to him. Sometimes wild animals can not be trained or trusted.
