Interesting! how does one get Olive eggs? I'm recalling brown egg+blue egg layer, but which needs to be hen, which needs to be rooster? Or is it a green egg layer that is needed (not blue)?
@Acre4Me,
To create an Olive Egger breed a BCM Cock that you know was hatched from a dark egg (#6-7, he’ll have a good dose of the dark egg genes) and breed him to a blue egg layer (Araucana, Ameraucana or Legbars). The F1 OE Pullets from this mating will lay olive eggs. If you want darker colored olive eggs then mate the F1 OE Pullets to their Sire to produce F2 OE Pullets. If you want Spearmint Colored Eggs then mate a F1 OE Cock to a blue egg layer to get a dull spearmint color. Hope this helps.
Take Care,
Keith
