Hybrids breed back to what the base breeds were. They do lose production because Hybrid crosses increase production as well as making them easily sexed by color.
I would hatch them! It is great practice and you can sell them if you have too many chickens.
Too many chickens?? No such thing!

What kind of incubator is everyone using, just for interest's sake?
I have an LG. Generally do very well with unshipped eggs (90-100%), terrible with shipped eggs (0 to 25%).
I have a homemade cooler-bator.... But I'm considering building a bigger one out of some cold room panels lying around... They are 2 inch styrofoam, with thin steel on both sides... I figure that would make a mean incubator... I have an STC1000 digital thermostat and a digital thermometer/hygrometer that I would then take out of the cooler-bator and install into the panel incubator...
