It’s funny, but you’ll find out that some eggs are easier to peel than others, why?
If you cook eggs the same day they're laid, you'll find it very difficult to peel them. Peeling becomes easier as the egg ages.
Why? but i also think that if the egg was cooked with salt its also easy to peel .
Does the salt method really work?
Salt will make the egg white not to come out too much when there is a crack. I don't think there is anything you can do to make newly laid eggs to peel well. I came across the link below that contains a lot about cooking eggs well:
