I bought a hen from auction and she has a yeast infection. I quarantined her for a while and fed her garlic and greek yogurt with her feed. After 6 weeks she was a little better but it started to get cold and I had to integrate her with the rest of the layers. She is fine with them and no one else has caught it but I feel terrible about her bottom. It is covered in mess and must get cold. We live in the south so it isn't so bad but I am desperately trying to find a natural remedy for this awful problem. Fortunately it hasn't affected her ability to lay eggs or act normal other than the crusty, stinky mess? Help!!
