I've been following you on here since day one and you are doing a great job. I keep reading what everyone is telling you and it sounds like they are giving you great advice too. To regards to your question about when you should let Rosey out and bring her back in again, I would think as long as...
You can get them at a fishing supply store or pet store. You can also feed her cooked or even raw oatmeal, soak it in buttermilk. The probiotics are really good for her and their is protein in buttermilk too. Don't make a big bowl just make it a snack for her.
