Looking good! I gave my boa 2 hides and blacked out the sides and back (and I have the front 3/4 covered for now with a dark shirt to help him chill), but I've also read that brbs are a little more shy than rtbs. Since all younger snakes tend to more skittish anyway, I wouldn't be surprised if you see her under the log. You'll know to get another hide or cover the sides and back if she seems defensive or reluctant to eat.
