I've done them, do them, and would do them again.

The MAIN THING TO REMEMBER IS THIS:

TRUST

If you can't trust the person you are doing the loan with, then don't do it.

It is all in the morality and the character of the person you are doing it with that you don't get screwed.

Too many things can go wrong that you and the other person cannot control...

And you need to trust the person taking care of the animals and the eggs to do the right thing.
