First Soft Shelled Egg

[Roomi the quail]

What season is it at your house? Could she be preparing to moult?

Can you syringe her some water with a little sugar or honey mixed in? Just to give her an energy boost.

Oyster shell pieces might be too big for her?
Save your eggs shells, wash them, dry them (in oven or microwave), crush them, then offer them in a seperate bowl for her at all times.

Answering previous questions:
-She lives in the cage beside my bed, so it's pretty seasonless for her. Fluorescent lights every time and no apparent malting going on. The temperature dropped to -13C outside, so it might have some impact though...
-She has her separate oyster shell powder dish and I started offering dried meal worms&vitamines as it's winter.
-Afraid getting another quail is not an option now I instead tried quail offline meeting a couple of times but she didn't seem to care overmuch.

Any kind of calcium supplement will work, as long as she eats it - calcium powder on meal worms is fine. Usually soft shells would be due to lack of calcium, and if she has low calcium levels that can also cause general weakness as calcium is needed for muscle contractions. There could be other causes for the soft shelled eggs though, so if the calcium supplements don't help, something different might be going on.

i am all new but here is a thought: before my major egg producer stopped laying in the end of the season the same thing pretty much happened:first she laid an egg that looked twice the size - it was double yolked. then she laid a soft egg. then another, then stopped laying and seemed distressed/acted egg bound, but then stopped laying and is as fine as can be. i think sometimes they just lay a soft egg as their ovi-bits prepare to stop laying for the winter.
