I have been reading the hatching page and really want to try it out. I am planning on either purchasing or building my own incubator. I am not going to buy eggs for my first hatch, I'll just use some of my mutt chickens. My question is that my roo is EE x RIR, my hens are all brown egg layers, (RIR, NHR, BO, BR, SLW, RSL). I understand that the link for green eggs is dominate. So my roo would be Gg (G= green, g = brown) My hens would be gg. So could I possibly expect 1/4 of my egg to hatch out as green egg layers? Or is that making everything to simple? Are there more factors involved?
