I ordered 5 silkies online and ended up with two marans and two silkies. They are supposed to be sending me more silkies at some point. One maran is a rooster, no doubt in my mind. I originally thought to put the marans with my full sized chickens when they were bigger, but I don't want a rooster with my egg layers. So I can do two things. Introduce the new silkies to the marans & silkies and make them a flock. That worries me because I don't want the marans to be brutal to the new silkies when they're big enough to combine. The second option would be to get a few more marans and have three flocks. My older hens I have no, have the whole front fenced in yard. The silkies are going in a tractor. I could put the marans in a tractor or make them a bigger yard. Any thoughts?
