We're new to chickens, and recently got 4 chicks: a Buff Orpington, a Plymouth Rock, a New Hampshire Red, and a Silver-Laced Wyandotte. Our SLW seems to be looking a bit like a rooster, especially because his/her comb seems significantly more pink/red than than the other 3. They will be 7 weeks old tomorrow. Could somebody give an opinion as to the gender of our SLW, please? Here are some pictures: Thanks!
