No more eggs?

[Chanee]

My three year old hens stopped laying eggs at the beginning of July They seem very healthy and happy. There isn't any place they could be hiding their eggs. Any thoughts or suggestions about why my girls are not producing I have only two hens, no rooster My hens were laying one egg a day consistantly for the past 2 years.
Thank you!
