I've had a hectic weekend and have only just caught up on Shad's thread now it's Monday morning.Well, just as I was feeling great about my tribes' overall health and the hens laying good eggs, this happened. These are Patucha's eggs over the past four days.

The two on the right have wrinkles on top and the one she laid this morning is massive.
She seems fine. I checked her out. Clean bum, vent is not swollen, red upright comb. She's walking around, foraging etc.
There are no signs of Infectious Bronchitis in these chickens. I've seen wrinkled eggs before from the hens I had before, but this was over three years ago. All of those hens have died -- and they had other symptoms like diarrhea, rales, sneezing, and very weak eggshells.
Patucha didn't live here until after the affected hens had died. I suppose it's possible that the two survivors (Cleo and Cheri) were still carriers, but unlikely -- I've read obsessively about IB and the the viral load drops to almost nil over one (minimum) and two (maximum) years after infection. I had a tiny closed flock for over two years. And I'm not even 100% they even had IBV. No necropsy. Just the symptoms matched up, so I kept just three hens until it *seemed* safe to bring in some new blood.
Patucha has none of the IBV symptoms, nor does anyone else, and these irregular eggs feel quite strong. I really don't think there's IB at work. But the wrinkles and sheer size of the last one ...sheesh.
I'd appreciate some input from anyone who may have seen this -- could it have something to do with the end of her current laying cycle?
I'm hoping she is at the end and will go broody, or perhaps she is going into a molt soon. She's not losing feathers, though. Patucha always goes broody about a week after Tina, and Tina went broody on July 27, so she's a bit overdue for a brood. She's laid a lot of eggs since weaning Solo (24 in the past 35 days) and I'd like to see her body get a break. She's about about 2.5 years old.
@Perris @Shadrach @MaryJanet @MrsNorthie @TheFatBlueCat or anyone else who's seen something like this -- thank you
Cleo's last eggs before she fell sick and died were also enormous and wrinkled -- but also thin-shelled , so I'm a bit worried.
(Edited to mention that IBV is often cited as a reason for wrinkles in eggs -- but I suppose it could be many factors)
At this point all I can do is add I've only seen wrinkles in shells from older ISA Brown hens who later had serious reproductive health problems.
I think you're right, reducing calcium a little may be effective.
