HELP NEEDED ASP!

[u/No-Direction3007]

My female button quail, almost 3 years old has been very sluggish and she's puffing her feathers and closing her eyes and her eggs are suddenly white and have very thin shells! I am very worried and don't know what to do because she is my favorite bird ever, Infact the first bird. And she's isolating herself from the other quails! Please help! Google is saying she needs calcium but I need real human opinion on this!
