Our 6 week olds have been eating Countryside Organic since birth up until 2 days ago when I switched them to DuMor. (temporary I hope,we are broke this week ) I know every 4th or 5th poop is supposed to be runny but now there is an excessive amount of runnies and they stink to high heaven. Nothing else is different, they are getting grass clippings,chickweed, and dandelion as usual. Countryside looks like real ground corn and seeds whereas DuMor looks like grey cat litter. In our old flock sometimes I would have to buy the cheap stuff from time to time and noticed the poop was super stinky but never caused sudden diarrhea. They are all still playing and don't look sick...
