You make excellent pionts. When I use chicken manure I use it in the
compost primarily.
If you are going to handle fertilzers you must know all of the health
risks, which I see you do.
My manure comes from a poultry company that runs a very clean operation
and has low disease.
I understand the health risks and I consider myself a very healthy
person, which I beleive play an important part in how any fertilizers
affect a person.
