Possibly Egg Bound

[Henniezues]

Hello! I love this website-it have been so helpful for us as we knew very little about raising hens not that long ago. I have a 2 1/2-3 year old hen that has a swollen belly and is noticeably walking more with a wider stance, not quite like a penguin as I have read. She is not moving as fast but will still run for treats and appears to be eating and drinking well. She also walks freely most of the day in the yard looking for bugs. I brought her in last night and could feel that her belly is distended and it looks like her vent is a little swollen. She has some hard, possible cracked eggshell pieces around her feathers below her vent but Im unsure if she is laying or not. We have 6 hens and they all lay the same eggs. i have noticed over the last week that there is one laying a very soft shelled egg and most times it is broken when I go to collect. She let me clean her up and put a little coconut oil around her vent last night but was very eager to get back to the coop. She pooped fine while I had her inside and was very vocal =) I have read several things including, checking inside her vent with my finger, giving her a calcium tablet, probios, epsom salt baths etc. I havent done anything yet as I wanted to get some advice first. Ive attached a picture of her vent although Im sure its probably not very helpful. any advice would be really appreciated.
Thank you!

I should have also mentioned that at least two of my hens are laying very large eggs(double yolk size but only single yolk) picture attached

Calcium with vitamin D is good, but some use Tums. Here is a brand from Walmart:

I tried to post this but I’m not sure I put it in the correct place. One and maybe two of the hens are laying very large eggs (they appear to be double yolks but are only single) Is this something I should worry about?

Update: I was able to check her for an egg in her and it doesnt feel like there is anything in there. I was able to get her to eat a calcium tablet and have her in a small kennel. The next day someone can check her out is Monday=( Im going to buy a smaller coop so her and Mama can stay in there and I can monitor her a litter better. She is now resting comfortably on a low heated blanket
