Hi!!! I was just informed by the roach guy and his wife in maryville tn, that u can actually tell the gender of your beardie at any age by looking at the back of their head. The line that goes across the top of their head is the giveaway. If the line is straight with a ? look in the middle of the line, it is a female. If the line is completely straight without the ? in the middle of the head, it is a male. Thats how you tell what gender they are before their gender parts come in. Thank you all, and i am happy to help. It has been correct so far, and we have ahad several baby beardies.
