I'm getting some new chicks on Thursday =) I'm really excited, but for one thing. The breeds I plan on getting are polish, and silkies,cochins, or houdans. My question is, how do these breeds do with large chickens? My rooster is 10 lbs, and all my hens are large. Will they be ok? Or should I get different breeds? All my birds are friendly, I'm just not sure if my rooster would hurt the smaller hens
