We got in 4 beautiful chicks 5 1/2 weeks ago from mypetchicken.com. A Buff Orpington, White Leghorn, Dominique and a Golden Laced Wyandotte. We are pretty sure that all are females except the Wyandotte. Pat, as we'll call her/him, acts more aggressive than the others and has wattles already. Can anyone tell me if this is a boy or girl? Thanks so much! This is my first post, so I hope I did the picture right.
