@MelissaRose Words of the wise: If you're trying to establish a new breed, using mix breeds as the parent stock is a bad idea. You need birds with known and sound genetics to even have a real shot at what you want to achieve.
Flat out, you really should invest in a better incubator. Whether you're doing this the hard way or the easy way, a faulty incubator is going to make your life hell.
New breeds were never established by cutting corners. Money was spent, years of effort invested and culling was heavily practiced.
Full cold hard honesty here, you have a much better chance of success by breeding a paint blue-egg-laying Silkie male to a splash Ameraucana female. Otherwise, you're mixing colors and are not going to be able to achieve a clean blue splash (which btw will have black as well by default).
This post isn't intended to be harsh or flaming. It's meant to relay the honesty of such an undertaking that everyone should know.
