Acknowledgement section should be as follows:

The authors would like to thank Doug Currie and Dr. Lauren Park of Roslin Nutrition Ltd. (Aberlady, Scotland) for conducting the layer study and formulating and preparing the layer diets. Our gratitude to Dr. Jason Keegan (Alltech Bioscience Centre (Ireland)) for project administration (animal science component) and initial data analysis (animal science component).

Author contributions’ section now is as follows:

RL formatted all data for downstream analyses, performed all statistical, computational biology, and bioinformatic analyses, applied computational approaches for measuring uniformity, devised the ϙ metric for measuring relative dispersion in productivity observations, produced all figures, formatted all tables, wrote the draft papers, and applied corrections as advised by other authors. AC coordinated sample collection, sequencing, and productivity observations. RM and FW provided research supervision and project direction.

All authors provided input to the corrected draft paper. The graphical abstract was produced under a paid licence with BioRender.com (2213–9170).
