So I've read in a few articles, both scientific and not, that female tortoises of some smaller species will develop a slightly flexible plastron when they start laying eggs. Some articles suggest this is adaptive, but without direct evidence, as it's also obvious that a gravid female will require more calcium. So, my question is, would you view this as a negative (i.e. it suggests calcium deficiency due to making eggs) or a positive (it's an intentional adaptation to prevent the female from becoming egg bound)?
