What kind of chick is this?

Makes perfect sense. I think I was slightly confused. Read what you were saying originally out of context I think and was interpreting it in that you meant " a bird with a crest genetically cannot also express muff/beard" BUT (LOL) that isn't what you were saying at all lol. I think it scared me and caught my attention because I'm considering an EE project that would make a bird that has a nice fluffy crest AND muffs and beards. Lol. So that was what prompted me asking. I was thinking maybe there was some kind of genetic conflict with those traits that I wasn't aware of. Lol. But you were simply saying with the breeds in the birds background it would not also have those traits. Thanks for the info and your patience and kindness! Much appreciated

I wasn't me that said it, but I do think you understand it correctly now.

Chickens definitely can have a crest and also muff/beard. That combination is found in Sultan chickens and in Araucanas in some countries (including Australia and England, I believe.) Silkies and Polish often have muff/beard to go with their crests too.

It depends on what the Legbar is mixed with.

Crested Cream Legbars have a crest, single comb, and yellow legs. They do not have muff/beard or a pea comb or legs that are blue or green.

If the CCL is crossed with other breeds that have single combs and yellow legs, the chicks will also have single combs and yellow legs, plus the crest from the CCL parent.

If the CCL is crossed with chickens that have muff/beard, or other leg colors, or other comb types, then yes those other traits can be in the CCL-mix chicks.

Because Ameraucanas have pea combs, muff/beard, and slate (blue) legs, it is common for their chicks to have those traits too, no matter what breeds they are crossed with. If they are crossed to breeds that have yellow legs, it is common to get green-legged chicks in later generations.

That is why Easter Eggers that descend from Ameraucanas often have pea combs, muff/beard, and green legs (they do not have to have these traits, but they often do). Easter Eggers that descend from Crested Cream Legbars will often have a crest, yellow legs, and a single comb (again, they do not have to have these traits, but they often do).

Thanks @NatJ. I think you explained it better than I could have
