ive got a mix of 3 week to 7 week old birds. a few birds are starting to change to look male (red breast) and a few growl when i pick them up (ive been told thats a male thing too). but none of them crow. they stand straight upright and puff out their chest and make this loud beedeep beedeep beedeep call. thats the best way i can explain the noise. is this the beginning of crowing? or is this an alarm call?
