Therese two have very small crests yoo, so they can see quite a bit better than my poor buff laced polish galyeahh..... I accidentally trained 2 of my polish girls to be aggressive like that. Didn't scold them when they pecked at legs and hands in curiosity and now they bite the worst out of most my birds. Males included. One will even do that rooster jump and kick and peck if you startle her. The Isabel is just too calm natured (around birds, not people) to really care
