get good food, scratch and lots of treats including meal worms

These same egg's shells are sometimes wrinkled in appearence.

I wonder if it's OK to eat these eggs. I googled and someone said maybe it's infectious Bronchitis!!! Any thoughts or info appreciated.

Do you have any photos of the wrinkled eggs?
Wrinkled eggs can be caused by Infectious Bronchitis, have you had any birds with respiratory illness within the last year?
As far as I know you can still eat the eggs as long as you follow safe handling and cooking methods.
You mention that you give food, scratch, LOTS OF TREATS What type of feed do you use? We all love to give treats and spoil our girls, but too much can dilute their daily intake, this can cause some issues of it's own, especially if they are gaining weight or have a generous fat pad in the rump. Do some reading and determine what is best for you, but a general guideline it to limit treats to no more than 5-10% of daily intake.
