I've noticed some poop in the run that looks like melted caramel and watched as it came out of one of my Buffs a few minutes ago. I have Ameraucanas and Buffs, 22 weeks old, eating layer feed, grit, scratch grains every three or four days, and occasional bread pieces. We just got our first egg yesterday, blue-green, so it was an Amer. egg. Put out oyster shell this afternoon. The chickens look and act healthy. Just wondering if I should be concerned about the poop. Thanks for any advice!
