If I understand their latest posts then yes, it looks like DSS/CPS is telling them they can't all live in the same house right now. I don't know if the parents of either set of kids have actually moved out. Heidi and Steve also run a business from their house called House of Macrobiotics. The FB page for the business shows the kids planting crops on the house's land and Heidi running the kitchen. They haven't posted on that page since mid-March.
the house of macrobiotics Facebook page clearly depicts a vegan family (nothing wrong with being vegan, but I’m pointing it out because they lie and claim they aren’t vegan). The house of microbiotics page also has numerous posts about how food is medicine, and that chronic illnesses like colon cancer can be cured with a plant based diet. I would bet they knew how sick Evanna was for quite some time, but insisted she would be magically cured by eating organic sticky candies and fruit.
