Definitely a roo right?

The age old question. This chicken (ameraucana) was part of a 10 chick sexed order. They were supposed to all be female, however I know that the odds are that a few will fall through the cracks. They are now about 4 months old and intergrated into the flock.

I feel like this one's tail feathers scream rooster but appears to not have a very large or red comb? Obviously no crowing yet.

I dont have a roosters and I live on 6 acres so having a rooster is no problem. I actually figured I would eventually get a roo even when ordering all sexed females. Just a little bummed the the one roo I got was a breed that would have layed blue eggs🫠
