A lot of times that's how breeder get rid of their bad producing pairs is by lying through their teeth. One or both the male and the female may be infertile. Or the conditions might not be proper right now for them to have babies. Sometimes it depends on their age as well, if it's a newer pair, practice makes it better!!! But why would you want to breed Quakers when they're illegal in a lot of states, the power companies remove their nests to prevent fire hazard, the babies are inside the nest that's being abandoned on the side, but most of the time rescuers are near by and takes the nest from them. It's very sad!!!! I used to have one and I love him dearly, one of the smartest little birds I've ever owned!!!
