A lot of breeders breed tufted to tufted. It doesn't result in 100% mortality, rather 25% mortality (since approximately 25% of chicks would receive two copies of the tufted gene, which is lethal), 50% tufted, and 25% cleanfaced. But other than that, you're spot on! All living tufted chickens are heterozygous for the gene, so some will be born cleanfaced. Rumplessness is also a dominant gene, it isn't lethal but it can affect fertility (it makes the cloacal kiss more difficult) so people often include tailed birds in their breeding programs.
FYI, still looking like a pullet to me! Hopefully she is indeed a she, if you want a pullet, that is!
