Chins poops are about half the size in the morning than at night, I would watch him for a day, see how he is, if he's eating, drinking, playing normally, and see if he poos are back to normal in the evening.
Morning poops and evening poops are often diffrent in size with morning being smaller. If you are really worried, get some acidophilus and give your chinnie some.
oh ok well i only noticed it this morning but last night it was fine and he seems to be eating and drinking just fine and hes like a 5 year old kid on a surgar rush. I guess I am just over reacting I have only had churro a few days
