first time posting, so forgive me if i mess things up. I have three of what I thought were all female chicks, yet as they have grown I think i have a little roo in the batch! H(s)he is a little bantam and is starting to make crow like noises and is even being somewhat of a jerk to my two larger ladies. Am i right? Is this little guy a roo? You can see him picking fights in the one below. Thanks guys!
