Eggs with holes

[Kitalvarez]

Hi everyone. One of my Golden Comets has been laying some strange eggs lately. She often lays ones with bumps (calcium deposits) and I don't really mind. I still eat them.

But lately, she has laid a few with these strange holes/divets in them, and I don't know what this is. I tried searching for another thread about this but couldn't find the same issue.

You can see there is some hard bumpy stuff inside the hole if you zoom in. I don't think these are peck holes. Also note the clusters of tiny dots on the shell and around the hole. These are more on the surface and most come off if I scrape lightly with my fingernail.

So what do you guys think this is?

FYI my chickens currently get Producer's Pride 16% layer feed, but are switching to DuMor Organic later this week. They have oyster shells free choice all day (but no ome seems to LOVE those) and they get fed crushed eggshells when I have them. They also get calcium-rich dairy products 1-2 times per week. They are nearly through their DE and apple cider vinegar de-worming. They show no signs of lice or mites.

I have a chicken with the same problem. The air sac is intact, but I discard those eggs. Our feeding regimen sounds the same as yours. I’d surely like to solve this problem.

What type of hen is she?

This hen unfortunately ended up dying from what I think was salpingitis. So did my other Golden Comet. It's really common with the production-type hens. That's why I don't get those anymore unless they are rescues in need of a home.

Before these hens died, I did try different treatments. Nothing helped, even antibiotics. I think for some of these production hens it's just inevitable because of how taxing daily laying is on the reproductive system and shell gland.
