Chicken laying shell-less eggs?

[Chicken Unboxing]

I'll start from the beginning; Remember our two roosters? Well, we went to the place we originally got them and traded them for two small hens, one white and one colored. (Genetically small, they are adults) So about a week ago we got our first egg from each. The colored one layed an egg just fine but the white one layed just... yolk. At first we thought it was maybe because she got startled or she had a lack of calcium, so we started feeding her egg shells. Now I wouldn't be writing this if the problem was resolved. This is the third time she has layed a shell-less egg and it really has me worried. Could you tell me the source of the problem and possibly a solution? Below is a picture of the second shell-less egg she layed in her coop.

What all and how exactly are you feeding?
How old are the new birds, in months?
How long have you had them and how did you introduce them to flock?

Well for the feed, I give them feed which I get at my local farm supply. It consists of cracked corn, barley, and some other seed I don't know the name of. For the age, I don't quite know. I think the folks at the farm supply said they were young but its hard to tell. I've had them for.. I wanna say about three weeks ago. We don't really have a flock it's just them two. We let them outside during the day in our yard with food and water and during the night we put them back in the coop.

If you are in the USA the feed should have a label that shows the protein and calcium percentages.
If they are laying they are at least 5 months old....but if they just started laying that might be part of the soft shell issue.

Update: My chicken laid this! Or well, I think she did. It was in her coop and at first I thought it was some sort of plastic, but I don't put plastic in there and it did look funny. I smelled it and and I can tell you it smelled like a month old expired egg... almost puked. I think my chicken might be sick. As of typing this right now my chicken laid another egg-less egg that was broken! Just yolk and egg white everywhere. Any ideas?

Feed info would be a good start.

I checked the bag the food came in but it didn't have any nutritional info, or info at all for that matter. I can't exactly tell since I get it from a local farm supply and it isn't all that professional, like a family business. What I can tell you is that it's mostly cracked corn, barley, and another seed, like I said before. I also give them egg shells from time to time, and maybe some tomatoes. I don't think seeds are a great source of calcium, so that I am worried about.

Here's a picture of the feed -

They have to have it on the tag by USDA law.
At the least I'd ask about the percentages.

I'll talk to them maybe.. next week? Tomorrow I'm going to a hotel! Just in case, I'll order some oyster shells for some extra calcium intake. If you could also lend some advice, while I'm on vacation, should I lock the run in case of predators or keep it open so they can come out during the day? I live in a town and my backyard isn't too big so predators don't come often... but better to be safe then sorry, right?

Depends on how predator proof the run is, and how big/small the coop is.

Mine would be allowed out in the run regardless if I'm home or not, but would not be allowed outside of the run.
