I'm guessing they are I was looking at my newly hatched & noticed I now have a tuxedo. My last batch didn't. Not sure which two crosses to make a tuxedo. But some veteran hopefully can tell us. I'm fairly new to coturnix. You picked the right bird I have Bob's as well & the Bob's are high strung compared to coturnix which are laid back. You can easily handle coturnix & if they get out of the cage you can catch them. Bob's get out forget it their gone.
