Used Homeopathic "Hypericum Perforatum 30C for my hen with Merck's disease and it worked!!! Thanks for a thread I read on this site! She was in so much pain I couldn't hold her to administer the pills so I put them in her water. Each day changing water and adding another pill or two. Within 3 days was walking much better. Within 10 days back to normal. Kept her isolated until all her feathers were back, total isolation time was about a month. Thanks for the info!
