Until I finish building her a larger cage, I planted some live plants in her laying bin to save some room. Is that ok? They are planted on the outside edges. The bin is 15 inches wide so she still has room to dig. The bin is only 11inches tall though. I know 12 was the minimum suggested but that’s all I could find that would actually fit in her cage. I did add more soil so that she has the full 11 inches to dig downward.
