This is one of the species prone to chronic egg laying., I've read many stories, some end up needing veterinarian hormonal therapy.
Diet is extremely important, to keep their bodies supplied with calcium and nutrition.
I do not have love birds. But I'm having eggs every breeding season in my quaker. My avian veterinarian suggested going to a 14-15 hour light day. And staying on that year round .using light and timer . That a long light day is better than a long dark sleep time in preventing seasonsl hormonal response.
I've only just started this .
Let her sit in eggs until she looses interest. You can get dummy eggs.
Sometimes when birds go to a new home , and d with other birds around ( or not) and are getting more attention. It can cause them to get temporary hormonal. I have seen this many many times. So we can hope it's just the excitement of the new home and this will be a once off. And this is not to dst to pay less attention to them or anything ! They are just happy
The other things, are after the eggs, increased forging, actives, moving cage every month, even by a few feet, re arrangements of cage , putting in novel objects. This little bit of change up , is thought to make it less their territory, a minor ( positive ) stress . I have had some luck with this
