The color of the chicks would depend on what color the rooster is (I'm pretty sure Pita Pintas can come in several colors), and what color the Olive Egger is (they definitely come in a variety of colors), plus whatever genes they are carrying but not showing (it's common for Olive Eggers to be mixes, so they carry other genes you can't see.)What would I most likely get if I have a Pita Pinta rooster covering an Olive Egger hen?
For egg color, half the daughters should lay green eggs, lighter than olive but darker than blue. The other half of the daughters might lay brown eggs, or they might also lay green eggs. That depends on whether the Olive Egger is pure for the blue egg gene or not. Of course the sons won't lay eggs, but they will have the same egg color genes as their sisters, and can pass those on to their own offspring.
