Let's start out from the beginning. I bought my 2 beardies from a girl who's bearded dragons had babys. She selected the ones she thought were female (ofcourse she couldn't be 100 % sure since they were 5 weeks old). I chose Viper and Spyro then. I have them housed together ever since, because I thought they were both female and sisters at that. And they never had any fights or problems. They are 1+ year old now and Viper recently lay eggs. It was a stressful moment, and we were very confused. So Spyro was a male? But no I reckoned the eggs were infertile and after checking I was pretty sure they were (I buried them) I tried gendering Spyro again, but it was pretty difficult to see. I wasn't 100% sure but I still thought she was female. After feeding Viper alot of grasshoppers with calcium and she regained her health, everything went normal again. Untill this morning, when I saw them mating. We were shocked, but I was happy and excited because last time I was pretty dissapointed that the eggs were infertile. Untill my friend reminded me of the fact that they are brother and sister. How could I have forgotten that small but very important fact?! I know I should seperate them, I do. But I really don't have the money or space to buy another terrarium. I really do not want to give one of them away. I really care about them. I also know it can be stressful for Viper (the female) and it's all so much worse because they're siblings. But can two females have sex? I know it's probably not the case but a girl can hope. Also exactly how bad is inbreeding really? Everybody I talk to says "It's pretty normal for animals, they do it all the time" but they aren't experienced with reptiles and online I read that I should indeed seperate them immediately and that inbreeding is in fact very bad for beardies. This is all so ****ed up :/ I really don't know what to do. Ps. I feel so guilty because now there's actually a chance that the eggs were fertile or maybe 1 or 2, I feel like a lizard killer ? But maybe it was for the best since they would be born from incest..
