i just had 15 bantam ameraucanas. those do look like boys. my girls had NO pink at all and not 3 rows either. i had 7 roosters. They are all 8 weeks now.
OMG...what did they turn out to be????? i should post pics of mine...they are just 4 weeks now, bantam version. so pinkish comb at this point relevant or not? most of mine has pink in combs. two don't....some have VERY long tails and pinkish combs! usually it seems like the bigger tails are girls!
