Giant rooster, Banty hens
Our 9 pound Maran hens and our 4-5 pound RIR hens where all the same size when they first hatched. The size of the roo doesn't effect the size of the eggs and chicks can't be any larger than the eggs they hatch from but with mixed genetic what happens to the chicks later as thy grow is anyone guess.
I large roo can be hard on a small hen but a small one can do the same amount of damage, it really depends on the individual roo. I would have a saddle (or three) on hand so you can use it at the first very first sign of feather loss.
I like these: http://crazykfarm.mybigcommerce.com/categories/CHICKEN-PRODUCTS/Hen-Saver%C2%AE--Hen-Aprons-%7B47%7D-Saddles/ but you can find them (both plain and fancy) all over the internet. If you can sew you can probably even find a pattern.

Also bigger rooster will not affect egg size correct? The hens will lay whatever their normal size is, the chick will just doubtfully not be a banty size, correct?
The hens genetic determines egg size, However with a mix breeding even if the chicks start off small but the chicks could just as likely grow to become large chickens. as they are to being small ones.
Since our hens roam around a large area I liked the snaps because they will release if the hen gets caught on a branch or something.
