Above are photos of moldy wood I received from a large company who sells chew sticks. I received not one, but two large orders which had moldy wood with the second order being much worse. The wood was only in transit a couple of days and was during a cool, dry time of the year. A good 1/4 of the boxes were filled with moldy wood. All of the wood had to be properly deposed of and removed from my home because of safety issues for myself and the animals. I was able to dump the wood a few days after I received it in a wooded secluded area . When I dumped the box out, it was filled with green fuzzy wood! The mold was clearly visable on all the wood at that point. Always check wood products before giving to your chinchilla.
