One of my Rhoad Island Reds was very lethagic and ust sleeping in the stall not roosting. After noticing this on day 2 or so i brought her inside to watch and was going to give her yogurt tonight. When my husband went to check on her he found her dead. She had been having white and green diarrhea and when she was found she had pooped liquid white and vomited some dark liquid. Any idea what happened? I want to make sure the rest of my flock is ok especially since i have a broody in another stall who's eggs should be hatching in 2 to 3 days.
