Our 3 yr old hens (barred rock, americana, production red) are all molting and have been for at least 3 weeks. For the last 3 or so days there has been NO poop in the hen house to clean up in the morning Normally, I would have at least 1/3 to 1/2 of the large coffee can that I use for clean up. I have seen only one or two poops in the yard. They are eating and look fine. Not surprisingly with the molt, we have only had one egg in the last 3 days. (Way down from last year at this time.) Could not find anything in The Chicken Health Handbook (Gail Damerow). No pasty vent on any of them. Before this occurred, the poop did not have a bad oder, I feed yogurt every now and then, especially when poop begins to have a bad smell.
