Is there any way to know what you'll get when you cross two different varieties? I have a Barred Rock Rooster with Brown Leghorns, Blue Silkies, Buff Orps, RIR and Americana Hens. We just hatched two clutches of chicks. The first hatch (3 weeks) came from the Leghorns and one from a Silkie. They all look like BR's...even the one with the tell-tale Silkie 5th toe. The second hatch (3 days) all look like BR too. If I let him mate with the Americanas, RIR and Buffs, will ALL have BR traits?
