Hello! I have 14 girls who are now approx 6 mo old. They have been laying for a few weeks now. Although the most I have gotten in a day is 12. My question however is that I see their feces and it all looks normal (formed and chicken poop like) but I see black diarrhea also. I have no way of knowing who it is but its consistent. I dont know if this is a problem or not? How do I know if this is a problem? I know it might be hard to diagnose because I do not know which one even has it. Thank you for your help.
