Have you had any issues with scaly leg mites from the leaves? Several of our birds got SLM this winter, not long after we started using the dried leaves for their litter. My father in law said we probably got the mites from the leaves. Perhaps from wild birds that would roost in the large maple tree the leaves came from. I'd really like to use up the 5 bags of leaves we still have but don't want to introduce any more mites!
