Is it true that 50% of F2 Olive eggers will lay brown? How does this work? I see people selling F2, f3 and f4 all the time and never saying much about chances of laying brown. Can someone break it down for me? What am I missing?
Breaking it down to... If you say they might lay brown then your sales would dip. Most seem to prefer that the buyer do self education before buying. Thus, I started breeding my own. For the F2 and beyond, I either dip the price to reflect the chances (with a detailed speech on how it all works) or hold onto them until they lay and tell me and then jump that price right on up to reflect that.
Some say that it's tied to them having a pea comb but that hasn't been the case.
Will a PDF file work on here? Attached is the most detailed egg chart for OE.
To make an olive egger you cross a blue egg layer with a dark brown egg layer.
The blue egg layer has two genes for blue eggs so it passes a blue egg gene to the offspring. The dark brown egg layer has two genes for non blue (white) eggs so it passes a non blue egg gene to the offspring.
That means when you cross the F1 back to a dark brown egg layer to darken the green color that the dark brown egg layer passes a non blue gene to the offspring and the F1 has a 50% chance of passing on a blue egg gene and a 50% chance of passing on a non blue egg gene.
There for around 50% will not receive a blue egg gene and will lay brown eggs.
