I have a flock of 6 chickens, all about 2 1/2 months old. I picked out a straight run Barred Rock, knowing there was a chance it would be a roo. Also a straight run bantam which turned out to be a Silkie. The rest were supposed to be pullets. One of my black "pullets" turned out to be a roo, and the Barred Rock crowed this morning. No idea about the Silkie's gender yet. But I'm wondering if I need to get rid of one of the roo's? Is the flock too small for two roosters? They seem to get along okay, one will challenge the other once in awhile, but the barred rock usually backs down pretty quick. Any help would be great, thank you!
