Same question, different chickens. These are my 53 day old (about 7.5 weeks) chickens, purchased as sexed pullets. How'd the hatchery do? This is Rose, my barred rock. He/she has always been the most aggressive, though by far the smallest. Comb is a little pinker than my more lady like chickens. Dorothea, an EE. I think she's a girl. Blanche, a buff orpington. Also a lady, I believe. No redness to her very small comb. Sophia, another EE. I think this is a cockerel. Walks much more upright (with a cocked up tail... is this a sign of a cockerel or does it just seem like one), has a pinker comb than the girls, with the 3 rows mentioned on these forums with EE cockerels. My only hesitations about calling this a boy are that he/she feathered quickly like the girls. Love to hear what you think. I'll have to get rid of any cockerels, but that's ok... might just add some already laying hens .
