Ahh BYC, thank you for solving so many mysteries. I know this threads old, but it's good. I was recently twice the victim of a stinky onslaught as I sat on my banana lounge, tapping away on my tablet. Two of my girls were free ranging right next to me when thick wall of funk slapped my nostrils; there was no poop, just two fluffy butts pointed in my direction. I was completely bewildered, wondering who, what and how. The second time was when I was locking them up for the night, and leaned over to check they were settling down. Again, another sudden thick wall of funk invaded my nose and slapped it around. They'd only been in there a short while, so again, no poo. My Australorp hybrid was making small clucky noises, so I blamed her. She might have been the one responsible for the initial round, so I now have a silent offender in my flock.
