I posted a few weeks ago about my hen that's puffed out and tucks her head into bet body often. She's about 36 weeks and has never laid an egg yet. She has a small pale comb still and doesn't have diarrhea. It was suggested to give her corid but that didn't change anything. I'm putting electrolytes in the water. She still is active but not as much as the other hens. No breathing issues and is eating and drinking fine. Any ideas?
