I have a feeling that this was the "Hatch of the Roos". Of 5 BB/barred rocks I hatched, 4 are roos. Since they were sex-linked, I could tell right away. The rest of my chickies isn't so easy. I don't know if you can even tell yet (being only a month old), but I thought I'd ask all you pros out there!
