In case you've never seen a 'soft egg', this is what they look like. There's a semi-thick membrane, but no calcified shell. One of my Partridge Silkies, Pearl, Layed this tonight. Normally a soft egg indicates something may be wrong. Since Pearl is recovering from egg peritonitis, and hasn't layed in a while, this is progress/good news. The white spot is just a shiny spot, not shell.
