I think I need to have my soil tested for heavy metals. I have chickens that have been sick for a long time and are not responding to antibiotics or supportive treatments. Also, when I run a magnetic roller over the soil after a construction project, I pick up many little black flecks. I am on the right track?

I hate to hear that you have sick chickens. However, it is very unlikely that heavy metals in the soil are causing them to be sick. They could have a viral infection. The only way to know would be to have one necropsied at the MSU Veterinary Diagnostic Lab.
