Good soil amendment?

[youngwilliam]

Hey all. I have lurked for awhile, and this is my first post here.

My question is, I have access to some interesting manure.
This person raised rabbits over a bed of peat moss and potting soil mix that was kept moist. What is interesting is that he grew worms in the same soil. He claims that he would just brush away the surface and their would be thousands of worms to gather. He sold them by the 40 worm cup.
Anyway, he had to stop due to heart problems about 4 years ago.
This mix has been sitting all this time under roof in the rabbit house. It has dried out and no worms are left.
Think this would be good to add to the garden?
Think any worm eggs would be viable?
He has allot sitting for the taking.
