It's difficult to see in the pictures. But here is an easy way to tell the difference. Look at your rooster, look at the feathers emerging from his back, just under the back of the wing section. Those feathers are long, thin, pointy, and shiny. Now look at the other birds, Girl's feathers in that same area will be short, round, and wide. Some of your birds look look like hens and some look like roos.... but in those pics it's hard to tell. But check those feathers, best way to check!Hi everyone! Ok I think I need some help...lol I have my 3 BLRW that I hatched on 8/11, I thought I knew what sex and colors they were but beginning to second guess myself! If anyone could give me your opinions on them and tell me what you think of them. I also have some pictures of my rooster that I believe is like 5 months. Sorry if the pictures aren't good but will keep trying!
