I’ve seen a few posts already talking about if pine needles are safe and i’m aware that they are. My question is if i cover the enclosed run, which gets very muddy when it rains, with pine needles will this be a problem. I know people use the needles for their coop but if i have it on the ground outside will i be damning my birds to mold and infection? I have a lot of left over pine needles which is why i was planning on using them, but if not i can seek out some wood chip mulch or sand instead.
