Egg bound with occasional shell-less eggs Opal Legbar

[RainbowHen]

Update - Thanks everyone. The added Vitamin D seemed to do the trick. We have gotten 7 blue hard shelled eggs in the past 10 days from Bandit! Also, after I had finally got an egg from Bandit Jun 28th, I was excited that I updated their nesting boxes with added curtains. Don't think that would have any effect on the shell hardiness - but the consistency seems like they are happy chickens.
