Thanks for the Valbazan info! I knew the piperizine was limited so it is time to switch.
The hen was one I had already that's been free-ranging. An adult, but not an old bird. One of my black split Orp hens. None of the new birds have been out yet and they are all fine.
I've never had much problem peeling boiled eggs, even boiled straight after collecting them. Boil them an extra minute or two, then take them straight from the boiling water to cold water. Peel them as soon as you can handle them.
