In a new study, appearing in Proceedings of the Royal Society B: Biological Sciences, scientists selectively bred Japanese quails into two groups: laying either relatively large or small eggs. As the quails don't do much "parenting" after eggs hatch, mothers' main contribution is the resources they transfer to their eggs (chicks from larger eggs are more likely to survive).
