I purchased 8 new hens from my local feed store recently., that were approximately 5 months old. They were added to my existing flock after a coyote attack killed 8 of my girls. The new girls are just starting to lay. Unfortunately, they ALL have runny, smelly diarrhea. They seem to be healthy otherwise but, I cannot get rid of the diarrhea. I first thought that after they were allowed to free range and eat better food, the diarrhea would clear up but, after two weeks and worming with Wazine, it is a no go. Still runny poo. Any suggestions on what I can give these girls to settle their stomachs? Thank you!
