What is easier to get rid of in a herd of chickens – from the recessive trait of the leaf-shaped crest or the dominant-feathered legs?

Naturally, it is always easier to get rid of a recessive trait than a dominant one. Let’s give an example: let’s say the gene a is responsible for the leaf-shaped crest, B- for the feathered legs we cross the owner of these two signs with a non-leaf-shaped crest (say, a rose) and unfeathered legs.
R: aaBB. ×. AAbb
G: aB. Ab
F1: AaBb -100%
Crest rose (Domin) and feathered legs (Domin)
We cross hybrids with glmozygots by recessive
P2: AaBb. ×. aabb
G2. AB. Ab.
aB. ab. ab
F2: AaBb. Aabb. aaBb. aabb
Only 50 percent of offspring with bare feet. And this is the second generation.
