The witch's chamber

In my interpretation of the story, the cannibal witch is too primitive for a bedroom or a bed. I want the upper chamber, her room, to resemble a bird house, because I imagine her to shift between human form and the form of a crow, a bird that does devour the young of other birds. So I have a craft store nest for her, and I was planning to use some dyed black feathers I bought and a skull and bones from a plastic skeleton, to set the grisly scene. But it looks too fake, so I'll wait until I have real bones from a chicken and some natural feathers. There's just her little treasure chest and a stool from a circle of wood I cut so far.  I left the circle windows open like the hole in a birdhouse, and there's a ladder and trapdoor connecting her upper room to the rest of the house.
