I got an EE hen about a month ago to add to my flock. She's suppose to be about 1.5 years old. After 4-5 days of settling in she laid a normal egg, then the next day she laid one that was thin-shelled which broke in my hand when I picked it up. Ever since then she's been laying them without shells. A week and a half ago she seemed to have one break inside her, so I brought her in and doctored her for a couple days, then booted her back out. Now back to shell-less. Her attitude/appetite/etc. has been great this whole time. Her poo and everything else is normal. It's just the eggs. Any ideas??? I don't want to have to make soup out of her, but if she doesn't shape up soon... ETA: She eats layer crumbles, free ranges, gets some treats, and has oyster shell available at all times.
