LOL, Pik I think that the calcium is like 15% in the mac and cheese. The highest calcium baby food that I can ever find. I feed it as a special treat, their normal jello is green beans, sweet potatoes, and carrots. They love the ham and cheese too thou so I think they just like the cheese. I know that when I drop a mac & cheez in there it is swarmed within minutes. I can drop the green beans or other veg snail jello in there and it takes them a few hours to get it. I personally think that it is the dairy product putting off a sweet smell to them.
The babies are looking great, and like everyone else has warned becareful or you are going to be over loaded with snails and remeber they poop alot.
DP's sound great they are what I am thinking about too, but I can't find alot about their setups. Still researching thou. Good Luck!
