Crowing at 6 weeks?!?!

[Chick Phil A]

Easter Egger rooster crossed with White Leghorn, I have 9 babies at 6-1/2 weeks and 4 appear to be male. At least one is already crowing, is this normal? The father crows both day and night. It might already be time to give away the males

Yes it can happen. I've had them crowing at 6 weeks. I've even read some posts of even younger males crowing as little as 1 week old. Seems like the right time to give them away if you can.
