Mike Novy (very respected in the industry) has had females pass eggs before. I'm 99% sure that my WTF, Shirley, dumped eggs herself, but there was quite a bit of blood in with the white things, so that's an anomaly; she tested clear of coccidiosis or other parasites, though, so who the heck knows there. I'm thinking the slimy white stuff you mentioned was probably frog skin.
