I have coturnix quail. My extras are 2 boys. 1 is a year old. He is brown - wild type coloring named Zombie. The other is a cinnamon/tuxedo-ish looking quail named Conan. He is only about 10 weeks old but full grown, fully feathered and crowing.
As for the crowing, it is actually cute sounding. Just not at 2am next to the bedroom window
