Could be, it's easy to overreact...and then spread the fear out of context...I must admit, I didn't know about the dangers of mold last year when I laid fresh chips (late winter-early spring). They were 3-4" deep with lots of rain, then sunshine. Those chips dried out fast. I also had young birds that survived and are thriving currently. Was I super lucky? Or is everyone else just paranoid... like I am now? I think it's contagious.
....and Yes, it is.
Like I said......
Not all molds and fungi are toxic, most occur naturally and are only toxic in intense concentrations(like TerryH's story).Not a common occurrence but best to let fresh wet chippings age a bit.....storing them long term does not present the same risks.
