I recently purchased 7 silver laced wyondotte pullets from someone to add to my flock of 10 blue laced red wyondottes. My blue laced reds are 6 mnths old and the silvers were supposed to be 13 weeks old. I have had them for a month now and this morning one of them seemed to be trying to crow. It doesn't look any different than the others as far as nothing distinguishing it to look like a rooster. These are the first chickens I have raised but the blue laced red I raised from 7 days old and I could definately tell the difference in them before they started crowing.
