Pullet laid soft shells then none for weeks

[Hope4Hennsyvania]

Good Day BYC friends & experienced hen keepers,

I have a question and am concerned for our almost 23 week old pullet/hen health.
She is a black sex link from Cackle hatchery, the biggest of our 3 pullets (all same age but different breeds), she is the bullied one as they other 2 occasionally peck at her when food/treats come out and once i saw her sleeping under the roost (i picked her up and put her on it, hasnt happened again) but she also seemed to take on some of a roos role, honking and protecting ...like catching a mouse or pecking and chasing away our dog & squirrels.
I read she could be bullied due to health, she's the only one not laying. They all started a few weeks ago within days of each other. While the other 2 girls are giving us an almost an egg/per day each... she dropped a few softshelled eggs a couple days about 3 weeks ago and none since

(we believed the soft shelled were hers because the other 2 girls still left eggs in nest box daily and we'd find 1 or 2 softshelled per day under roosting bar. Idk if they can lay a good egg & still create a softshelled then a good egg within 24hrs, but im not experienced and just going by what ive read)

Anyhow, my question.. is this ok for her, To have laid a few softshelled a couple weeks ago and nothing since? Will she start laying? Ive already thought about it altho hoped/planned for 3 laying hens we will not get rid of her even if she doesnt, she will stay. Is she sick, or defunct?

Shes eating & drinking, active & curious, They free range in the yard all day from 8am until dusk. She's got different poo then the other girls. I found a post about whats "normal" and shes at the far end but within range
Also, she's the only 1 that doesnt want to be touched, catching her is very difficult to even check her out. She will eat out of my hand, even prefers it, and.comes running when i bring out food but if I try to pet her... she quickly moves out of reach

Im worried she's unhealthy and do not want her to suffer if I can help her. Also have a 10yr old daughter that would be distraught if one dies unexpectedly.

Soon theyre moving to little bit bigger coop, i dont expect them to be happy about the change but wondering if it'll help her to reestablish a spot in pecking order or will just make things harder for her in what I see as chicken highschool cliques. How do I go about this move, do you think theyll prefer it with more space, height and longer roost or will they want the old coop, do i have to hide the old coop so they dont have a choice?

I want to provide the best life I can for animals in my care and appreciate advice.

Anyone have a chicken like this or have any suggestions?

Sorry if this post is all over the place. Thanks all

Your hen could have a faulty ovary, not releasing yolks. It could also be hormonal. Have you noticed her comb fading a bit in color?

It can also be a vitamin deficiency. Vitamins A and K3 are crucial for laying. These can be found at pharmacies selling people vitamins. I get mine at Walmart or order from Amazon. Calcium citrate would also be a good idea since her shells were thin. Is she getting a commercial feed? It's well balanced for all the nutrients chickens normally need, but the A, K3 and calcium could be lacking in her system.

I would give her the A, K3 and calcium until she starts laying good quality eggs. However, if there are no results after a couple of weeks, it might be best to halt the vitamins as the days may be too short to re-trigger laying, and try again sometime in February.

Here's more information if you are into chicken lit. https://www.sciencedirect.com/science/article/pii/S1751731121000847

Thank you and Yes, she and the other 2 have a main diet of store bought feed which is available to them all day and I also mix some with water and give it to them 1st thing in AM then again around 6pm to ensure they're eating. I was using Dumor starter/grower until a few weeks ago, she laid soft shell so same day I went to the brand w highest calcium I could find. Now theyre all eating Purina Layena. The other's shells are very strong. I attached her photo taken this morning. Her comb looks red, but sometimes looks a little "dry" if that makes sense.
I'll put a pic up w her next to other 2 girls to compare

Also, the do have a light on their coop that is on until 8-830pm, so they'll have a constant 12 hrs+ hrs of "light" even if partially artifical. Their new coop will have a window so they can see get natural light inside in winter.

What can i do to help if it's a hormonal/ ovary thing?
