Hi there, I have a wonderful 4-H girl that has offered to take my roosters for me. I know that I have one boy for sure, maybe 2 or 3. I would like for them all to go together, and don't want to accidentally give away a girl. I have checked once before, but not that everyone is a bit older, I would love to get more opinions. If you know that one is 100% a boy or girl, would you mind letting me know. Thanks so much! They are 13 weeks old.
