By allowing the rooster to even approach the toddler with a pane of glass between them, you are allowing him to continue his aggressive dominating behavior. It's only a matter of time before he does injure this child. And a child in a stroller is especially vulnerable. The child is restrained in a face forward position. I beg you to get rid of this rooster.I would get rid of that bird or pen him up. Very dangerous behavior with a small child involved. It only takes once for a spur to get in the eye for irreversible damage to be done.
