Look at the 3rd post above yours. It says that green mixed in with the wood chips adds to the fungus problem that can kill chickens. They will probably be OK after they've aged and dried for a while.
I just checked and the remaining 4 came through OK. Whew... I remember when reading that thread from cover to cover that I was afraid the others might not make it. But they did thankfully.
Great pepper.
There was a long thread a while back about someone who used wood chips and had some problems with mold. Maybe someone remembers and can link to that thread.
