no shell egg

[sonomachicks]

My 8 month old BR has laid 60 eggs since January. However, she laid a no shell egg on Thursday, and has not laying eggs for two days. She did use the nesting box though, but just no egg come out. I checked for stuck egg under her abdomen, but it seems normal. She is eating well, and getting a lot of worms in the yard too.
Is she sick? Should I be worry about her?

I had a soft egg too, the other day, from one of my 12 month old hens. First one ever. They are acting fine, I put a cup of oyster shell in there after the fact. From what I've been told, it can be normal, and not symptomatic of anything. I'm just keeping an eye on them, watching for anything else unusual.
