Hi friend,
You likely were sold a pair that will not / hasn't ever had success breeding, and you may find it likely you won't find success either. Doesn't mean it will never happen but breeders don't usually get rid of pairs that can make chicks (more profit to keep them if they're good breeders) so it's likely you'll have little success with the pair. Just my 2 cents.
Ekkie eggs start hatching at 26 days, so at this point it's just beyond the normal hatching range and the eggs are likely NOT going to hatch. If you aren't aware of Eclectus incubation periods, you need to do much more research, it's incredibly novice to go into this entire thing without even knowing how many days you need to keep an eye out for with the chicks. Keep watch of the eggs for the next week, if they don't hatch, its' time to toss them in the garbage as they are not going to hatch past day 35! It doesn't happen and anyone who comes at me to say let them keep them 2 -3 more weeks please don't bother (chicks rarely hatch after this 26 -28 day mark period), so a few days extra is essential, but there's no need to keep the infertile eggs for weeks on end.
Infertile eggs happen for a lot of reasons, and the breeder likely saw this pair would not produce chicks to profit on what they were hoping was a good pairing. But as it turns out not all pairs are successful. But I wish you luck in successfully getting a fertile clutch.
After you toss the eggs, the pair will likely start trying to lay again. It's important that, whether or not the 2nd clutch is also infertile, you give this pair (both male and female) a REST and take that nestbox out for a couple months. A couple clutches a season is normal, but letting them breed year long can and will cause poor quality chicks as the hen never gets time to rest and replenish her own nutrients.
Why don't you get to know this pair, bond with them and learn about their behaviors/characteristics before letting them breed again?
