http://www.tpchd.org/page.php?id=111 If you're in Washington, you've probably seen the commercial "Dirt Alert". I just recently saw it, and apparently there might be lead or arsenic in the dirt. Would this affect chickens? I just have started letting my two chicks outside so I'm a little worried that they might be especially vulnerable to this. Let me know, two of my chicken-keeping friends also are worried as well.
