Hi Dusty,
They haven't paired together male and female, the two males believe they are a pair and the two females believe they are a pair, if the eggs are fertile it means that one of the males have cheated but they cuddle up to their own sex not in pairs..
There isn't anyway of me finding out which has paired with which unless i watch them 24/7 both the females have resulted on laying on the eggs now and it seems to me the males are going in the nest and eating them. They have six cuttlebones planted around the cage plus millet spray plus grit of all kinds mixed together with egg food and rearing food.. Not a lot else I can give them. I never brought them for breeding so its not a big problem. As I said I don't know which one to separate them with.. One of the males is just a big bully and its the other male sleeps eats drinks baths with him they build their own nest together etc
