Bad eggs?

I wouldn't shake an egg. I'd toss it if it smelled, if not I'd wait.

It depends on if all the eggs went under her the same day, if so I'd probably give up on the others.
Are you sure volunteers weren't added later?

A candeler is very easy to make. Take a hooded heat lamp, put a fluorescent bulb in it, cover all holes on the hood with duct tape, then cover the top over the bulb with a piece of cut to match open end of light with a hole cut out large enough for the egg to sit on, but not fall through. When it gets dark, candle them to see what is going on. At this point, you should see some movement in the egg and maybe even hear them when you put them to your ear. DO NOT SHAKE THEM. My broody took almost a week over her due date, I attribute that to the inconsistency of her setting. Up, down, hens changed, etc. Good luck!
