So I am wanting to get my first beardie but the only place that sells them within a couple hours away is a Petco. I walked in to check it out and 3 of the 4 dragons were relatively active. One was basking on a log and moved towards the glass when I walked by. Another was climbing on a plant and watched me as well. The third ran around a bit and also reacted to me. However, the fourth one was obviously unhealthy- it was not sitting up like the others when I held it so it sort of just layed limp on my hand, was noticeably smaller and skinnier, did not react even when I tapped the glass, and didn't move anything other than its head the whole time. I am just curious, what is the chance this bearded dragon is infected with something putting the other 3 at a higher chance of also becoming sick and unhealthy? Should I just have one shipped from a reputable breeder or take the chance with Petco?
