One of my rescue adoption hens, Maeve, the EE, had been laying a nice sage green egg about 3 times a week, since mid February, but stopped laying abruptly about a month ago. She's very handling adverse, so I left her alone for a couple of weeks, as she was acting fine and is an older girl, so I hadn't really been expecting her to lay much. I did grab her a couple weeks ago though, to trim a poopy butt, and check her out. I discovered a swollen abdomen and with palpation I could feel a hard, egg size mass. I thought she could be internally laying, and a trip to the vet earlier this week confirmed it. So this morning I dropped her off at the vet to have surgery, to remove the egg material and oviduct. It went well, and I'll be bringing her home on Saturday. So yesterday I tried to get a few decent pics of her, just in case things went sideways. She's camera shy, and I'm not much of a photographer, but I did get a couple decent ones. Also got pics of Celeste, who is definitely not camera shy, and Barbie, who is also not camera shy.
Sounds like you have a good vet, so lucky!
, and then feel like I have put in a full day by 11am and really need a few hours' nap to survive till anything remotely like a proper bedtime 
(None of these hens are their broody btw, and I am convinced that they really do not need her protection, although she would surely disagree, and sooner or later an adult will get fed up with them - when they exit the cute phase, like toddlers do - and then they will be banished to the bottom of the pecking order. Meanwhile, mealtimes are easy.)
