I've suspected one of our young "hens" is actually a roo. Although it has no spurs, and a small comb and wattles. Some of my known hens have larger combs than it. And I thought all roosters had spurs. It's around 4 months old I think. My wife called this morning and said she heard crowing coming from the run. Do hens ever crow like a rooster? And if it is a rooster, do I need to keep it separate from the hens if I want to eat the eggs? Thanks!
