I am getting into keeping quail myself but have owned other pet birds before. With the size diff I would of worried about bulling before putting them together but they seem to benefit each other, I do love seeing that.
I would use a very little bit of coconut oil just enough add a little gloss but not gunk her up, it should sooth if its from over matting which I suspect more then the other options and if its external parasites it will kill any it comes into contact with. After that I would provide some food grade DE for a dust bath, this will kill all parasites that it comes into contact with yet is fully safe as its fossil sand. and finely I would add some brewers yeast to there food it wont effect there yeast balance in a negative way in fact living yeast of this kind like baking yeast can be used to help balance bad yeast. getting a bit off subject the brewers yeast helps repel further parasites down the line.
I don't know if more feathers can come in before a malt (I think they can)but once she malts she should look like none of this ever happened of course after looking worse all over for a little lol.
Again I don't own any quail as of yet but this is stuff I have picked up in my studies for ecosystem establishment/maintenance so its kinda wide spectrum info that may not apply. I hope some of this was helpful and not just a mess with how I go on.
