I have a chicken pooping a brown diareaha (sp?). I don't know which one, there are 9 in the coop. I wouldn't have noticed it at all except its on the coop floor. None of my flock seem sick. All are eating really well. Only one is acting kinda crabby, but she's also 5 months, so I think maybe she's gonna start laying soon. But what should I look for sick wise with the birds? I have time tomorrow, I can sit outside with them and observe to see if i can see which one is doing it... Should I worry? Or are they kinda like people, occassional runny stools?
