I've noticed recently that some of my free-range chickens have started producing blue feces (blue when it would normally be a more olive green). I haven't changed anything feed-wise. I have put lime down on some patches of the lawn where I had ducklings caged--to keep flies and dogs out of the resulting mess ducklings make. Could the chickens be scratching in the lime and that is somehow changing the color of their feces? The best way to describe the color is the same blue as rat poison, but there hasn't been an poison put down around here. Any thoughts?
