This is off topic, but could you use Marraduna EO hens to make sex-linked chicks? If so, which kinds if sex-linked crossings could be made?
 
I think you could use the roosters for a sex-link cross over silver hens, I am considering doing this with a cream legbar roo over Delawares - should produce a crested hen that lays green eggs

Delawares actually are barred so you wouldn't get sex links. You'd get some pretty cool black barred chicks though!

Delawares are genetically silver, and can be used in red sex-link crosses - Gold male over Delaware female produces males with the Delaware pattern and females that are red. I have heard that the down difference is subtle, though.

That works because there is one barring gene--Marraduna also have a barring gene so not a sex link cross. Would you get a sex link if you crossed with a New Hampshire and a Marraduna?
 
For red sex-links, you use a Gold (eg RIR, NH) rooster over a Silver hen (eg White Rock, Delaware, SL Wyandotte) , barring is not important - Cream Legbars are also barred. The male has two sex-linked recessive gold alleles(s+/s+), while the hen has one dominant silver allele (S). All male offspring will be S/s+, therefore silver, while the hens will be s+ only, and therefore gold. If EO's are s+/s+, they can be used for this kind of sex-links.

Black sex-links use a non-barred rooster over a barred hen, such as RIR or NH over a Barred Rock hen. The female must carry the sex-linked barring gene, and the male must not carry it. Any non-barred non-white male will work in this cross.
