I bought a beardie 2 weeks ago, don't know how old he is but he is about 4 inches. He was cool the first 4 or 5 days that I had him and know he tries to jump out of my hand every time I have him. I have also noticed that the last 3 or 4 days that I have had him I will try to get him before bed time and he will puff up at me and open his mouth and run so that I can not catch him. Is this normal behavior and if so how long does it last? Do I just have a stubborn beardi?
