Misshapen and oddly sized eggs

[Orange Chicken 22]

This past week, my 2.5-3 year old red sexlink, Penny, started laying weird eggs. The first one was slightly longer than a normal egg. The next one was the same but also had a few spots where the shell had holes. Today she laid one with a ridge around the middle of it, like a belt. I know its her because she lays in my goats' hay basket while I'm doing chores. This morning, her best friend Rose ( same age & breed) joined her and laid a big bloody egg. She was a little ruffled afterwards, but is acting normally now and isn't bleeding anymore, and her vent looks normal.

I'm getting two or three more eggs a day from my other hens, and they're all normal, but I'm thinking something has to be up for two hens to be having problems. I'm feeding Nutrena 16% layer pellet, and they have about an acre to roam. I've read that it's either a calcium deficiency or excess, and am leaning toward deficiency, but I wanted to get a second opinion from you guys.

Another note about my flock is that they are likely positive for infectious coryza (an autopsied pullet was positive), but I don't know how that would play into the giant egg.

Do you provide crushed oysrer shell for your hens to take freely when they need extra calcium? It sounds like you hen might be having body checked eggs or some mineral deposits. Can you post any pictures? Here is a good article about many of the common egg mistakea, and what possible causes are:

I don't currently have oyster shell for them, but I will if I need to.

From to to bottom: normal egg( from another hen), bloody egg(Rose), pinhole egg(Penny), and banded egg(also Penny).

Here's a close up of the egg with holes and the banded eggs.
