I once had a hen that did sit long enough for an ostrich egg.
I hadn't given her any eggs, because I didn't want chicks, but she seemed to be healthy enough so I just kept letting her sit. She did eventually quit of her own accord.
In that case, definitely i+ (no Dominant White)
I don't know about what genes affect eye color.
Probably:
s+ (gold)
Mh (Mahogany, makes a richer red shade than just having gold)
E^WH (Wheaten)
Co or Db or both (Columbian or Dark Brown, both restricters of black)
i+ (no Dominant White, also no...
I had not been reading this thread. Did you post pictures of her somewhere in it?
Assuming the color is red all over, without obvious black or white, I would expect:
gold gene (s+), not Silver (S)
probably Wheaten (E^Wh), but several of the other e-locus genes may be possible
Likely Columbian...
