are you sure the "mold" you are seeing isn't actually the fuzzy little root fibers? they look a lot like mold but are actually part of the plant. if you look closely the root fibers rather evenly coat each larger root strand, whereas mold will be clumpy and uneven. it can be really hard to tell.
Ya it was fuzzy white mold not alot but some, I took it apart to look closer. But I read that mold wont harm your chickens si I wasnt ti worried.
