Last year was my first time raising turkeys. I got 6 BBB , as soon as the 5 toms started strutting and gobbeling, the one hen, killed them off. We know it was her as we saw her. she killed 3 in one day! After that we let her free rainge, she killed one of my chickens (hen) that she had been having issues with. Is an aggressive hen normal? She tasted great at thanksgiving weighing 17.6 dressed out.
