Just purchased 3 new hens, 2 are of the same breed, 1 of a different breed. All are 16 wks old. The person I purchased them from, got them from McMurray hatchery in the brown egg layer assortment. I still can't place them even after looking at their site. Any ideas? The seller thought maybe a Pearl Leghorn (but the comb is still very small) and 2 Marans (but they weren't listed in the possible breed assortments).
