I will post when they start looking better.
I have quail too. Texas A&M and brown courtunix. They are not likely to sit. I know of one person who said theirs sit, but she had a hidden dark place to sit. I personally think they are too close to wild to sit in captivity.
Mine has some mottled feathers also. From what I have read, laced birds sometimes are not really "developed" until after a molt or two. I do not know from experience. None of my laced birds have molted yet. That is a long wait.
I have two GLW and one does not have enough edging around the feathers and the other has real thick edge around the feathers. They are pretty but miss that desired SOP. What's really funny is that they are both ditzy. One walks past 3 nice buckets and digs a hole in the dirt to lay her egg in and the other goes across the fence to the neighbor's yard and can't figure out how to get back home.
That is OK , I just like to look at them and gather the eggs. They are all such fun!
