I have 5 banty BRs, almost 2 weeks old. I have heard that you can sex BRs by the white markings on their heads. Now I know this may not be all that accurate, but my brooder's too full and I need to downsize, so I might as well rehome the ones that have at least a reasonable likelihood of being roos! So here's a nice shot of the backs of everyone's heads: Of the 5, 3 of them have bright white feathers at the tips of their wings and big, bright white bottoms. The other 2 have little or no white on their wing tips, and their bottoms are less white. You can see the white wingtips in this shot: So, if you were looking to pick out the roos and keep the girls, based on their markings, who would you keep and who would you give the boot?
