Why did you mix the Wyandotte in there? Why not just go Ameraucana to Andalusian?? Assuming you could find an Andalusian with lacing...lol
Wyandotte has a double copy of the lacing gene. I have growing out right now Blue Andalusian that have a double copy of lacing. They are only 5 weeks old. I will have to get pics of them. Once you see them, even that young.................you will see a BIG difference in what I am saying between edging and lacing. It is really hard to get rid of the white earlobes from the Andalusian also, that's why I add the brown egg layer gene. Since its a cross with a white egg layer, I will get very light to creme color eggs. The earlobe will be at least light flesh to waxy white. Rose combs are hard to deal with too, when it comes to crossing. That is another good reason to mix them first. It has been the best luck so far. I am getting white skinned, flesh earlobes, no leakage, single gene beard/muff, laced pullets. On my F1, to me, that is awesome. They look like Ameraucana, you can't even tell they are a cross really. If you look at my pics that I have posted of them. They are a little dark toned in blue, but they are definitely laced. Another thing to look for when breeding for blue, if you are using black or splash birds, you should be able to see the lacing or in the current case edging on the breeder birds, to move on to the next generation. It is hard to see this effect on a picture.
I also want to add something, the color of the bird, is not the most important trait. Please look at your SOP, and check out the break down of points. Use these as your guidelines when breeding. I also love the fact that I am getting hybrid vigor. I am not losing size, or egg production either. So I think, as of right now, its going really well!
