Glad to hear that the hen is doing better,
@BigBlueHen53.
I lost one of my old girls. Went out to feed and she was belly up under the roost bars. Probably about 8 7 or 8 years old so not surprised. She looked healthy enough. Of good weight, crop full, no signs of prolapse or being egg bound. Probably a sudden death heart attack. Told DH that the way things are headed I'm going to wind up with a flock of roosters before all is said and one.
Colloidal silver is great. Our vet recommends it for wounds when our cattle dogs get banged up. A couple of drops directly on the wound to speed healing. We use it on wounds ourselves. Silver permeated wound dressings were coming into vogue shortly before I stopped working clinical. I agree with
@WhatsUpDuck. Look into Colloidal silver.
