Ok both of these 1 RIR and 1 Easter Egger are 18 weeks old. They both are larger than my other 4. Neither of them are crowing or even trying to. But the RIR has started trying to mount one of my barred rocks. I have read that a dominant hen will do this so I am still questioning. They don't really act like I've read Roos act. None of my girls are laying yet. They were all supposed to be pullets. I edited to show some pics of the rest of my flock for comparison.
