I hope Loretta gets better soon.

I did end up giving her another calcium supplement to no avail.The dose can be twice that. Calcium encourages contractions to help get an egg out. I would give her another calcium dose a little later if she hasn't produced anything.
Her crop was empty the following morning, although it felt empty when I brought her in in the morning as well.Check to see if her crop empties overnight by early morning after not eating or drinking for 8-10 hours.
In all honesty she didn't feel as though she was overly full. (If she would have I would have commented back)If fluid builds up too much in the abdomen it starts compressing organs and can be fatal. If she seems really full and heavy back there I’d watch some videos on how to drain a chicken and see if that’s something you’d do or would take her to a vet to do. There are a number of things that can cause water belly (ascites) and the prognosis isn’t always good. Reproductive issues are common but it could also be heart failure or liver issues and probably other things. If she doesn’t lay an egg or improve and you can’t take her to a vet, I’d drain her and treat her with antibiotics if you can find them in case she has an infection and to prevent infection from the draining. I have had one chicken recover from a bad case of ascites that hasn’t had a problem in years, but frequently it’s a chronic issue and sooner or later the bird dies from the root cause, though I’m really hoping this is just a blip for Loretta.
I appreciate your insight, thanks so much.I'm so sorry this grief has struck at just this particular time. Unfortunately, chickens don't get sick at convenient times. Do to the yellow poop, I have a strong hunch this hen may have been laying internally. If you were to open her abdominal cavity, you might see a collection of "hardboiled" eggs that had reversed course in the oviduct and spilled over into the abdomen instead. This can happen to new layers and older layers alike. There is nothing we could have done about it.
