I got two straight run chicks this year and have had them since the day they hatched (I did my best to pick females based off of some of the sexing hints I found online). Now they are 13 weeks old and look exactly like little hens. My polish's crest and saddle feathers are round, she has no comb, no red feathers at the shoulders. My tiny silkie has a round poofy crest, no comb, no streamers, is extremely docile and tame. She general walks around in a squatty position. (Both chicks are bearded, so they have no waddles). I know with these hard to sex breeds they say you don't know until they crow or lay an egg, but at this point, with absolutely all signs pointing to pullet, can I make the call? I would love to stop worrying as we can't have roosters.
