My new Americauna has laid a couple with wrinkles. She's also popped out some soft shelled eggs that break. They have access to oyster shell and I also have a bin with rinsed and dried crumbled egg shell but sometimes they don't eat it. I've started giving her calcium citrate with vitamin D. I pry her beak open and shove it in.I wonder if that condition is indicative of something else?
I got two more this morning.

I had another I had to do that for, usually once a week. She had a shell gland problem so her eggs looked like someone stuck the shell together with a seam around the center. When she was older the extra calcium didn't help and she eventually got a reproductive infection.
