I had one of my RIR's with diarhea. I was feeding lots of greens and some yogurt, banana for treat, pomegranate, apple. I stopped with the extras for awhile and gave only scratch, 17% laying mash, sunflower and niger seeds and water. It seemed to clear up a bit and now, she has it again and has been losing weight. Another chicken now has it. One has watery green and the other (the thinner one) has white runny. Help.
