Those sound like they may have been lash eggs, which aren't actually eggs, but rather expelled masses of infection. That would be consistent with salpingitis.Before I threw everything away and cleaned up, I found one of the yellow "shells" that was further along its way to becoming an egg, and indeed it looked just like the rotting, soft-shelled eggs I used to often find. Brownish that was darker at one end and mixed with black speckles. Unfortunately I do not have any pictures of that or of the eggs she used to lay.
