I think with societies as with any species of finch the success of rearing chicks is condition of the birds. There are many things to consider and often overlooked by the breeder when caring for foster societies.
1 - Make sure the societies are in breeding mode.. which is what you are trying to trigger with a dummy egg. Your hens may be responding better than the males because they are responding to the trigger of the egg. The males may not be in breeding mode... what triggers birds is hormones, courtship, nestbuilding..and of course for him...the act of copulation. If males are allowed to court and breed the hen they are always good fathers , I have found.
With just adding eggs or a chick just won't be enough to trigger parenting...though if the pair is in prime breeding mode, you can put just about any egg or even chick in their nest and they will foster it.
2 - Are the bird old enough. Many times breeders don't respect the need for maturity in societies because they are many time bred young and figure they just don't need age for maturity. However their best parenting skills are like most finches and perfected from 2 to 5 years of age.
3 -Proper foods to raise the fostered young. Many waxbills need much higher protein than the millets that societies prefer. So conditioning societies to eat eggfoods, chitted seed, and bugs is important if you want to rear more demanding chicks with different dietary requirements.
4 - Overbred societies. This you have already expirienced and mentioned, Gary. Just like any finch they need their rest time to recharge, molt, etc.
Most breeders that have success with foster societies are usually the ones that have allowed the societies to breed themselves...intentionally or not. How many times have we read on these post..."well , they slipped one of their own in this clutch"
That will actually make them more parental. Or many breeders allow the societies to lay their own clutch and then substitute their own eggs with a different species, discarding the societies eggs. Both of these methods are pretty sure to be foolproof. Of course you may find a society confused about a fuzzy baby if they have smooth skinned chicks in the nest. They may sense something is wrong with it. This is remedied by always removing their eggs and replacing them with fuzzy chick eggs. This way that is normal to them.
Zebra finches come in handy here as fosters since their chicks are fuzzy anyways.
There is a real art to honing good societies. Sometimes you get lucky and have a conditioned society at the ready when needed, and sometimes you do run across that amazing society that will mother anything, anytime, anywhere.. the super Wo s

I have always found these to be hens.
