I ordered 4 sexed chicks from MPC. They are now about 7 weeks old, and I am almost 100% sure one is a rooster. I can't decide if I should keep it or not. On one hand, I really wanted 4 hens because that's the quantity of eggs I can use. Also, I have a toddler and infant, and I've heard that roosters are too aggressive to be around young kids. On the other hand, this rooster has yet to be aggressive (although it's pretty much still a young one, too). And I've heard roosters protect the flock. (My birds aren't free ranged, but they occasionally spend time in my 1/4 acre backyard.) I am not worried about crowing. It won't bother my family, and my neighbors aren't close enough to mind, I don't think. If it makes a difference, this rooster is a salmon favorelle.
