My olive egger is a Marans/Ameraucana mix from mypetchicken. She is a cruddy winter layer and she makes more noise than the rest of my flock put together. Her sister is the same. It's not all that fair to rate "olive eggers" since different mixes will have different traits but this is just my experience and the particular mix I got. If you're concerned about upsetting your neighbors or if you're trying to hide chickens from your HOA, this might not be a good mix for you. When mine are laying, they are good for about 4 olive eggs per week and neither have gone broody.
