Is there a magic food that make hens plump eggs nonstop? !

[Majd]

We have a veri beautiful hen that layed about 10 eggs last spring. .. and the same the year before... then sge spends the whole year relaxing and enjoying life.... I have no problem with that.... because I love my chickens as pets as well as egg gifters.... but I want to hatch some of her eggs soo bad... she special to me... and I heard people saying that they got some king of feed and their old hens were laying like production layers... and the ones that don't lay so often were laying an egg a day.... is there something that does that to a chicken??? Is is harmful for them? And if there is. What is it?
Thanks everyone

Do you know what breed she is? Some breeds lay very low number of eggs.

Give her good quality layer feed, fresh clean water, a stress free environment and a well-kept, regularly cleaned coop and she will repay you, if she is physically able and in good health.
