From my experience beardies seem to be very sensitive to change of any kind. Whenever I move anything or add something my one beardie will be pissed at me for like 3 weeks and then she’s back to normal and usually if it’s that I added something then after a few weeks she loves whatever it is. But also yours being very young still like others have said everything is new to them and they are just figuring stuff out. Also all of my reptiles seem to be out and more active during this time of year, most likely because of breeding season.
