I picked up (rescued) 4 beardies today that have been kept together for the last 5 years. 2 females and 2 males. I have separated them but they seem rather agitated and calm down again when all together. I have never known bearded dragons to do well in groups so should I keep them apart or put them back all together. They were being kept in appalling conditions and are all malnourished (working on fixing that). Any advice?
