That is good news about the endive. Make that your staple. They should get that as the bulk of their diet daily.

Your diet definitely needs tweaking or your animals will run into problems. Here is one of the better diet lists that I have come across, but there are some questionable food items in the staple section. I do not consider collard greens to be safe because they have a fairly high amount of oxalates. the mustard and turnip greens do as well, so endive and escarole are your best bets for staples. And the dandelion is an excellent daily component as long as it does not have chemicals on it. Also, be sure it truly is dandelion. Lots of plants look like dandelion, but could be toxic.One other thing that you should try to add is edible flowers that are safe for herbivores. Hibiscus is a great one as are nasturtiums,roses, and of course dandelion.
