Ok- the Welsummer chick with the big comb is obviously a roo and so is one of the buffs- they are about 10 weeks old. The other buff I'm leaning towards roo as well. The blacks are all about 9 weeks old except for the smallest one and the barred one- those are about 7 or 8 weeks old. I am leaning towards pullets for everything except the buffs and welsummer. Whatcha think?
