How to tell the sex?

[Poppafrog]

Ive got 13 RIR that are about 10 weeks. How do you tell the difference. When do roos get spurs? I only need 1 rooster and out of 13 I bet I have more than one.

You should be able to tell by how big their combs & waddles are, roos have bigger ones and will be more red, neck feathers come in later on roos and also look at their saddles to see if the feathers are different, roos usually have longer pointier feathers on their saddle. Spurs come later on around 6 months or longer. You will know for sure when you hear crowing, mine started crowing at 11 weeks.

The cocks will have big fat legs. Here's some reds the ones with the big red wattles & combs are cocks.
