Dragon ranch on another world

[shadowstep25]

It’s set in another world on a farm or ranch where they raise dragons. When a group of dragons was about to hatch the main protagonist, a young boy steal one of the eggs and hides it then makes a mini farm with some type of firegrass that dragons eat but if humans touch directly it burns them. Later in the story it’s found out that he stole the dragon, and I think some other child was introduced as well, they were then hunted by the people who owned the ranch. The dragon got injured but they got away. However the nights on that planet are extremely cold so the dragon which was dying made a choice a cut open it’s stomach so the children cold hide from the cold. The book ends with the children coming out of the stomach and finding out that the dragons blood changed them.

This is all I can remember about the book. If you know or can find out the name of the book or author then I thank you deeply for the help.
