Iv researched on and off for about 2 years (essentially when ever I caught some chicky fever I was overwhelming google with questions). But the side effect is that I have run across many different ideas about raising chicken's. So I'm just a tad bit confused... At what age EXACTLY should we be very sure that our chick's are (hopefully) female? And What should be the first sign? The second? ect. We have 2 Plymouth Rock chicks, lilly and Violet the twins, 1 (I'v been told) Easter Egger, Jazzy girl Jasmin (she is the smallest) and 1 Road Island Red, Rose. The twins and rose are BIG the lady said they were 1 week old and now they "should" be 2 weeks old but MAN they are BIG for 2 weeks old. They have lot's of feather's. Still downy on the body but yah.... The EE is much smaller and was sick when we first got her home. She is doing much better now though. She is half their size and even has a different temperament. I swear when I tickled her tummy last night I thought I saw her do a chicky like laugh... Any way's we wont have the heart to cull them if they are boy's... oh I hope they are girls.
