I'm so sorry that you lost your hen. I hope things go well for the rest of your flock.Hi!! Busy with spring chores. Just took plastic off the run. Power washing tomorrow. Came in here to look for a recipe. I was going to use 6tbson peppermint Castile soap w/vinegar in a gal of water. Hope all is well at your end. I did loose my RIR. Not sure if respiratory or what. I treated her like I did another hen. Gave her a soak in epson ..I was drying her, she vomited brown liquid
