I just ordered 6 buff's and 4 guenia's. I have 4 adult buffs, 2 adult barred rocks and one a adult mystery girl who raised my last 9 baby guenia's. When I bought the babies the hen came as a package deal so I have no idea how old the guenia's were when the hen took over.....Question is~~~~When my day old babies arrive can I put them with the hen or should I brood them? I have never had day old's before. Thanks much for any advise.
