Puffed Up, Heavy Female Finch?

[Coturnix Quail]

I got my male finch (Pikachu) 3-4 years ago. His mate, Moltres, died about a year or two ago, so I got him a new mate. Her name is Poot, and she's white. She's layed quite a bit of eggs and I give her boiled egg and treats every now and then, but last night I noticed she was puffy and sleeping before I covered them. I could touch her, and they're not even tame, but she flew away a couple seconds later. This morning she was on the floor, so I scared her up, and she didn't seem as fast as she was before, she's less active now, and something seems to be weighing her down. She still comes for treats though. Does anyone know what's wrong?

Could she be egg bound?
Have you been supplementing some calcium since she's laying so many eggs?

Maybe? When I do feed them eggs, I give them quite a bit. I'd say half an egg at most. That was my initial thought, we'll see how it goes. I'll feed her some more egg this afternoon. I feed them crushed eggshell too, but it seems only Pikachu eats that.
