Turns out my 3 month old Brahma is a too, and I'm questioning if the Wellsummer I bought with him is also. My White Leghorns turned out to be Sussex, which I like better, but I am also wondering if one or both are Roos. The Plymouths I raised with them are the only two out of 6 laying, and the ones I suspect to be Roos look the part. The Plymouths and Sussex are 4 weeks older than the Brahma and Wellsummer.
