We live in Seattle where roosters are not allowed. So we bought our chicks from the local grange, that buys only sexed chicks. We've had them for 4 weeks, and turn off the lights for half an hour each day (as instructed in the Storey's Raising Chickens book). When I turned on the light yesterday, one of them crowed. It was a little chick crow, but it sure sounded like it was preparing for the real thing. We have two Rhode Island Reds and two Buff Orpingtons.
I have a 6 week olive egger and he is already practicing his crowing....cute right now but won't be when he finds his big boy voive. They are funny though, because I had an Ameraucana roo (he was very tame and beautifully coloured) and he didn't crow until 5 + months. Sounds like you might have a roo too....no pun intended.
I raised some straight run light brahamas and the boys (7 out of 9) had a couple who crowed at 8 weeks. It was a very very pitiful sound. Lol. But it was cute.
Sexing is usually only guaranteed 90% accurate by the hatcheries. If you know which one it is, the grange might let you bring it back and exchange it. Some stores and sellers do.
