Chicken only laying yolk!

[ChickenGals13]

I have a plymouth rock chicken who had been a steady layer with good large eggs but for the past 2-3 weeks she has been laying just yolk and sometimes there’s a very thin shell in the coop. Her only other symptom is that she has a bare belly which is a recent discovery on my end. Let me know what you think it is and what I can do to help her! Thanks!

Edit: she has access to both grit and oyster shells

Did you change her feed in the last few weeks?

Did you change her feed in the last few weeks

It’s the same kind if that’s what you mean and if you mean for freshness it should be good I change and clean it out it regularly - Also all of my others are laying normally

I have one like this too. Following

It seems like she has a problem either with her shell gland in the oviduct, or not getting or absorbing enough calcium. She is at risk for a reproductive infection or salpingitis. Is she on a layer feed as well as having access to oyster shell daily? I would get some human calcium citrate with vitamin D, and give her one tablet daily for the next 7 days. You may use other calcium or Tums if that is all you have. Let us know how she gets along. You can use this one or another:
