What about a male Owlbeard over the ladies?
Egg color of daughters should be about the same.
The crest/beard/comb part should be the same no matter which direction you do the cross:
I would expect chicks to have beards (inherited from Owlbeard mother), although there is a chance of chicks without beards. I would expect combs to mostly be double: like a V-comb or more likely resembling a Buttercup comb, but some might look single in front and split at the back or some other odd combination. Chicks from a Cream Legbar father will probably show crests. It looks like Owlbeards have small crests, so chicks with an Amberlink father would also be expected to have small crests. I can't say whether the crests would be big enough to notice, or so small they don't matter at all.
Example of combs from a V/single cross:

(First post of this thread has photos of a chick with such a comb.)
Lemon Owlbeard hens with Cream Legbar rooster: chicks will probably have cream-and-black or lemon-and-black coloring, probably with patterning of some sort, and white barring across it all. The "patterning" might look like bad spangling, or bad lacing, or bad double-lacing, or maybe something that isn't really any of those.
Legbar hen/Owlbeard rooster will give chicks like what I described above, except that only sons will have white barring and daughters will not.
Lemon Owlbeard hens with Amberlink rooster, all chicks will probably show bad single lacing. That might be black lacing on red/gold/lemon/cream color, or black lacing on white, or white lacing on red/gold/lemon/cream, or white lacing on white. I would expect all four of those in approximately equal numbers. All chicks would have some chance of red leakage, no matter what other colors they have. So for example, males might have dark red shoulders even if the rest of their coloring has no red.
Amberlink hen/Owlbeard rooster should give sons that show silver (white) and daughters that show gold (red/gold/cream/lemon.) The patterning should be what I suggested above, and could be in white or black on both males and females. So these chicks should be color-sexable (gold female, silver male).
barred rock, blue rock, Silver Laced Wyandotte, Amberlink, and olive egger hens
Owlbeard rooster should give duplex comb, muff/beard, tiny crest to chicks in all cases (unless he carries the gene for not-crest or not-muff/beard, in which case some of his chicks will lack those traits.) Chicks with single-comb mothers should show some form of duplex comb, although it is likely to look bigger and less tidy than his, because he has two duplex genes and they have one. Chicks that inherit pea comb or rose comb from their mothers may not show visible effects from the V-comb gene (duplex), or they might have some splitting of the comb (which might look really odd.)

This post shows a chicken with both V and pea comb genes, with a V/single one in the background.
V comb with rose is giving me trouble. I haven't turned up any photos yet, and I'm tired of looking.
Owlbeard rooster with Barred Rock hens should give black sexlink chicks (daughters black, sons black with white barring.)
Owlbeard rooster with Blue Rock hens should give blue or black chicks (either color can be either sex.) There is a chance of chicks that show blue or black patterning on a red/gold/cream/lemon color, with patterning being in the same range as the Amberlink-mix chicks have.
Owlbeard rooster with Olive Egger hens should give some black chicks. They might also produce chicks of other colors (I think I predicted that with the other roosters too.)
Any of those "black" or "blue" chicks may show leakage of other colors as they grow up. That also goes for ones with white barring on black.
Owlbeard rooster with Silver Laced Wyandotte hens should give sexlinks (gold daughters, silver sons.) I would expect all chicks to show black single lacing on the silver or gold ground color. The "silver" males may look yellowish as they grow, and may get red leakage. For the "gold" females, there is a chance of them being bright gold or even red, but I think lemon or cream color is more likely from that cross.
Egg colors with Owlbeard rooster should be almost the same as egg color with Amberlink rooster, but with a bit less brown in each case.
