All three budgie hens have continued laying eggs. Maude stopped laying at seven, but Astrid and Tiffany each have eight. I expected Astrid's ninth egg today, but it wasn't there, so she might be done laying. In any case, the chicks are due to start hatching soon, and I have not yet had a hen lay an additional egg once she has a chick.
(I didn't bother Maude to get a photo of her box.)
