My rhode island red hen began having exceptionally watery, green poop. It smells much, much worse than usual and I can smell it from outside and away from the coop. She always goes to the bathroom in the same place, also, but now she's just pooping in the middle of the coop or wherever. She looks healthy other than this, but something is definitely wrong. Please help!! F.Y.I. Pictures of chicken poop ahead, for those who don't wish to ruin their appetite.
