So you sent your guy to get 4 chicks and he came home with 10? It sounds like he's an over-achiever!I asked my guy to only get 4 RIR chicks for us, hoping for 2 or 3 hens. Well!!! He decided he'd go ahead and get 6. But 10 came home with him.. Watching them over the months, I judged that we had 5 males and 5 females, but thought that I would know for certain very soon as they would start crowing. Again I say WELL!!! The girls started laying at precisely 5 months. But you know how life goes. When when you want a males cooperation............................... Now I am not new to chickens. Just new to RIR. I have no other roosters.
P.S. I just realized what your member name says...love it, lol
