Free Range Rabbits

I know this has been spoken of several times, and I've read several posts.. But...

I've decided if I do, this is what. Now is the choice good?

I live in New Hampshire and deal with weather. Have 3 acres of land, so space to work in something.
We do have Fox around, so have to be penned.

Reality time please!

Not a newbie to raising live stock, just not going to deal with 'Free-range'.

Best of the best ideas of pens, food, dealing with climate and predators.

Have you ever considered to cultivate spirulina for rabbits?

Here is some studies of using spirulina as food to rabbits, you have to search the texts since they cover also other farm animals:

As your rabbits make poo and litter as byproduct, you can compost them and use the compost tea as nutrient for spirulina!

The main problem is, that compost tea is very dark and makes the spirulina water dark too: so light cannot penetrate anymore so deep in water.

I am working in solutions of this, so hope to get some results in this summer.

If you got interested, there is a topic about spirulina growing here:
