Anyone have this issue before? We currently feed them layer crumbles supplemented with whatever is in the yard and of course oyster shell and grit. Occasionally BOSS and scratch. They're great for the frying pan and baking but hardboiled is awful.
I use this method on extremely fresh eggs and it never fails.
Boil the water first. No salt or vinegar added. Make sure it is a hard rolling boil. Add eggs cold from the fridge. Boil for 13-15 minutes, and then rinse in cold water.
Peels perfectly, even using eggs that were laid that morning.
