Most of my tiny flock have mild to moderate mucousy diarrhea (white-ish). None have a change in activity, egg laying, ect. That's right, no other symptoms. I changed their feed out of need a week or so prior. It was the same brand but I was all organic and this was not. No, I am not an organic Nazi. It just represents a change in content of their diet. My question is have others exp this? For those curious: The old feed is available again and they are being fed that, I added probiotic to the water, and am cleaning butts. I'll let ya know how it goes.
