It can be hard to tell gender wit EEs and OEs.Not sure about the gene.
Once ours was a few months old and feathered out, there were
some people who questioned her photos until she actually layed an olive egg. She hardly lays any eggs (5 over
the past 3 months) and acts very protective over the flock. Not sure what I have, but a keeper
regardless. Am glad I hung onto her, because I almost got rid of her when some people first told me she
looked like she had sickle (I think that's what they are called) feathers.
Good call holding on to her!
