abnormal eggs - what is the cause & should I be concerned?

[faymine]

Hello, my 8-9 month old female coturnix has been laying abnormal eggs recently. As seen in the picture two are shell-less and the third one has a thin, very fragile shell. Today no egg was laid.

She has a high-protein diet and I provide her with calcium supplement. She eats 1 mealworm a day.

She is not displaying any visible signs of illness, but I suspect it's egg drop syndrome or she's reaching the end of her egg-laying cycle for the winter.

Should I be concerned? What steps could I take to help her, if any?

What are you giving her for calcium? Are you offering it on the side or is it part of her feed? You might try switching her over to a layer feed that has the calcium mixed in.

We used to get these many years ago. I give ours calcium in a separate container and sometimes I mix it in with their feed. I would add more. I add more every day. I fill it back up after they go up for the night so they have it come morning. The birds do not have enough on their own.
