They are already laying on top of each other, they aren't doing that because they like each other, that's what they do to show dominance. It's a classic sign of issues, you can look this up. We're just trying to save you the problems you absolutely will have if you don't separate them, as they are already showing the behavior that is an indication is trouble...And it's not all about fighting or "becoming nasty", not at all. In fact, most issues that occur with bearded dragons living together start as very young babies showing just the behavior yours already are, and here's what's going to slowly happen to yours if you don't separate them immediately: slowly over the next few months one will become more and more dominant, while the other submissive, and the submissive one will be robbed of the best feeders, best basking spots and heat, and most of all, the submissive one will be under tremendous stress every day, all day. And then suddenly you're going to realize that one of them is thriving, normal size, healthy and happy, but the other is stunted, lethargic, and you'll think that she's getting sick...But she's not "sick" per se, she's just been under such tremendous stress her entire life that she's actually becomingly physically effected by it, and it's finally bad enough that she's showing outward signs. That's usually what happens, that is if you are lucky enough to get away with no physical aggression and missing toes and tail nips. This is the major issue that occurs in probably 90% of bearded dragons forced to live an unnatural life that totally goes against the way they live naturally in their wild environment. IT IS MOT AT ALL LIKE DOGS, LOL, please don't make that analogy as it's completely wrong. Beardies come together to mate then immediately separate for good. The mother lays her eggs and leaves for good. The babies hatch and separate immediately for good. And they all live their lives completely alone, 100% of the time, except for the very short time it takes to mate. So you're forcing them to live unnaturally, which absolutely does cause them both stress until one takes the dominant position, which has already started to happen with yours. So if you know this, why in the world are you even attempting to risk their health and possibly their lives? I mean, it's totally unnecessary to do this, it's irresponsible, and it's unfair to both of them because they do not want to be together with any other dragons, they want to live alone. It's just the way it is.
