I'm just wondering if it's possible to tell the sex for sure on my chicks at 5 weeks? I was originally thinking the one on the left was a girl and the one on the right was a boy but they are both so much larger than the other chicks and are growing at a much faster rate so I'm not quite as sure now. As you can see, the girl has a much longer tail and the boy has redder ear lobes and a more noticeable waddle which you can't quite see in the photo. I was originally going by the size difference in the combs as the boys comb was slightly bigger and had more red in it
