We have 6 babies that are about a week and a half old and I am wondering if one of the girls might be a boy, or maybe it's too early to tell. When I put my hand in the brooder, this one chick runs straight over to check me out and when I hold the others, she stands guard and watches me the whole time. After I put the held chick back in with her peeps the one on guard rushes over to check them out. Now is this normal behavior for girls or do I have a potential rooster on my hands? Thanks!
