I rescued this chicken a few weeks ago. No clue of it's history. Super sweet. Missing top beak and some neck feathers, but is eating well and on the mend. I started to introduce the chicken to the rest of my flock. Seems pretty aggressive, has tried to pick a few fights. Still keeping mostly separated from the others. I'm pretty sure she's a hen. I've never had a rooster. She does crow a few times during the day. My lead hen in the flock does crow once or twice in the morning, then that's it, but this one crows more often. I think it may be a Delaware? Not sure. Any thoughts?
