Dumb question about blue eggs genetic

[Altairsky]

I have a cream legbar rooster that I got from a reliable breeder. Then I got an araucana hen from a not-as-reliable friend which, even if she was born from a blue egg, she lays green.
Her sister, born from a blue egg, lays pink.
If I mate the CL rooster with the green "araucana" egger, will I have 100% chance of blueish eggs?
Should I always select for pea comb to be 110% sure?

And if I mate him with the pink egger that was born from a blue egg, do I still have 50% chance of blue eggs and 100% chance of either green or blue eggs?
thank for the help!

You will get bluish or greenish eggs. Selecting for pea comb won't be very beneficial because in the Legbar, single combs are linked to the blue gene unlike in Easter Eggers where pea combs are linked to it.
Mated to the pink layer you will get 100 percent greenish eggs.

In case I need to cull my CL rooster and keep one of his sons, if I mate him with my green-pea-combed hen, would it be better to still keep the pea combed boys or it makes no difference?
