I have had my brothers Bearded Dragon for about 6 months now. He is in the military over in the far east. I have been taking care of her. She has been acting really strange lately. Seems to be digging on her playsand. I got to speak with him breifly this morning and he said "maybe she is looking to to lay EGGS!" how is this possible? She has never been around another dragon? I searched the forum here and have seen posts about infertile eggs. Can this be possible? She is about 3 1/2 years old.
