Please help...I am at my wits ends. I lost 2 hens last week and I have another hen that is acting fine but has loose stools. I am a naturalist so I don't use meds to worm. I got them 3 weeks ago and all had normal stools. So this has developed recently. I feed the Layena and scratch and of course table scraps. Yesterday I gave them a natural priobiotic remedy of yogurt, scrambled egg, molasses, and garlic. I gave them pumpkin the day before. Today I ground some fresh coconut. I reluctantly added an antibiotic to their water supply as a preventative. Does anyone have any suggestions as to what it could be or what else I should do? Thank you!
