I have a 3 year old white leghorn hen laid egg without shell today. I had one before get infection from this last year. Forgot how to treat hen so she doesn’t get an infection. Any info?
These membrane eggs are sometimes called "stress-eggs". My chickens lay these when I first get them, and they are too stressed to correctly produce an egg. Sometimes, it just happens for no reason. I'm surprised you had a chicken get an infection from one! Mine are always fine after laying them. when my chickens get infections, I give them apple cider vinegar in their water, and I also give them colloidal silver. Hope this helps!

It's not uncommon for an egg to be laid without a shell. Chances of another infection is not that great since such eggs are laid with membranes. Just be sure to feed a good diet. Oyster shell also helps provide calcium.
Was it a fully formed egg just minus the shell? Just a yolk? Any membrane at all? I personally would supplement her calcium ASAP (starting today), for several days- a week. Even tums will do in a pinch, But 1/2 caltrate +D3 is better (although 10x more expensive). If she was just starting to lay I wouldn’t be alarmed, but at 3 years of age it could be a reproductive problem such as your other one had. internal laying, salpingitis, etc . You may want to do an internal exam (with glove and lubrication) to see if anything was left behind in there.
+1 to exactly what @staceyj said. Get this girl on calcium ASAP and see uf it helps. Has she had any respiratory symptoms in the past?
