Chick 3,4,and 5 came from a breeder not TS and he said that they were sexed pullets. He had 2 brooders of chicks one with roos and one with pullets- I am not sure if his guess were acurate or not, but it is sounding like they might be...
I have been leaning towards male with chick 8 for quite some time, with every noise, he/she chirps loudly and stretches his/her neck way out, whereas most of the other crouch down and scatter.
