I have three, 3 month old Austra whites one has a much larger comb and wattle than the other 2 and much redder. But he doesn't crow and it's feather pattern seems to be the same as the other 2. I want a roo for my flock and have one lined up for free, but don't need it if I already have one. I'm a 1st time chicken owner so I have no clue except for what I read. Thanks for any help! .
