I went to check on my ladies during evening rounds, after all were roosted, and saw this poop under one of my hens on the roost (confirmed by "leftover" mess on her bum fluff). She is slightly puffed but alert and responsive. I've never seen a poop like this in my coop before. It's hard because they've been stuck inside for a while now that the weather has been so frigid. They have clean water and fresh food and a radiant heat spot to warm up near. Any advice would be very appreciated!! I don't want to treat for an ailment until I have an idea of the cause (worming vs antibiotic etc).
