Wow, I didn't know there was such a difference between male and female. Thanks Frazzermrat1! Also, since I now know that I have a cockerel, what do you think is the time it will take for him to be dominant in the flock? I haven't showed the four chicks to my four adult hens yet, but I plan to within the next week or so. (Currently my RIR hen is boss).
Sorry to bother you again, but my mom has had bad experience with roosters as a kid (hyper aggressive, chasing her around) and doesn't want that to happen again. Do you have any advice as to how to start him off well early? Can I raise him to be a gentleman?
Thanks.
