Today we've cleaned out the hen house, washed the nest buckets, & I'm burning the 27 trillion infinity pine needles in the hen yard. My question is, what cleaner do I use to clean out all the old hens debris, so my new babies have the best start possible? Do I even need to give it a good scrub, like with soap, water,& white vinegar? My old ones died, so we're starting from scratch again.
