Ganoderma Posted October 30, 2007 Report Share Posted October 30, 2007 slightly off topic, but the title is Egg not bird eggs... when i was breeding reptiles i noticed, especially in lizards, that the amount of calcium intake (and therefor the amount used in egg production) directly related to shell hardness. some animals that had very little calcium (especially those that have already laid a lot of eggs in a season) would lay eggs that are sometimes almost opaque ad quite soft. then theres the ones that are laying for their first time in the year, for example, and are stuffed full of calcium sometimes had eggs so hard the babies had a hard time breaking it. also i found Vitamin D3 and sun exposure had some differences but i never really looked into it that much, but that is directly related to calcium. but reptile eggs are far different from birds eggs many times. most reptiles rely on an egg tooth to break the eggs, usually meaning softer eggs while birds got them big honkers to bust through with.
