It may work for you, only time will tell about the dragons. I will agree some may be completely ready at 12 months, and may be done growing fully. But, alot of dragons keep growing, or keep developing. Whether it is bone structure that is still growing, or actual size, you may not even know that your dragon is still developing. Especially when the calcium that the female needs for bone growth is being used for egg development. Not to mention the other side effects that CAN be associated with early breeding. And the other side can be harm/abnormalities with the young dragons and eggs. Again, if that calcium isnt there because the female needs it, or deosnt have it........you can lead to further problems with babies as they develop and dont have the calcium/vitamins they need. Not arguing, just showing maybe why it is better to wait, or to give the advice to wait till the female is a bit older. Chris
