I switched my chickens over to layer feed six days ago. When I did I noticed a caramel colored softer poop in the run. I thought maybe their stomachs were upset with the switch so I gave them some plain rice for a couple of days. The new poops were gone. Today there seem to be more of these different poops. The girls are active and eating and seem happy. Most of their poops are the same as they have always been. I'm not sure if it is just one chicken or a couple. Is there something in the layer feed changing the color for some of the poops? Or is this a normal ceacal poop?
