My tiny little flock consists of 6 White Leghorn pullets (and 1 Silkie but she isn't kept with the Leghorns.) I'm looking to add to my flock, & there's a local guy who raises Rhode Island Reds & Barred Rocks. I'm looking to get 6 more chickens. Which breed would you suggest I get to integrate with the leghorns? Or should I get 3 of each? And is there any easy way for me to sex them as babies? I wouldn't mind a roo, but I don't know what I would do with more than 1.
