Are they housed together?
Bearded dragons are not very sociable with each other, and do better when housed alone.
Sometimes even being able to see another dragon with stress them out.
If you have them housd seperately, I'd reccomend having them out at different times, and not trying to mix them together.
Also, when you get a new beardie it is advisable to quarentine them from your other dragons for at least 30 days, to avoid spreading parasites or diseases.
Your new beardie is also going through something called relocation stress. It can last upto a couple of weeks from when you brought him home, and it's best not to handle him too much in the first few days in order to let him settle in properly.
If you'd like to go over your set ups for us, we can see if there may be anything that's stressing them out.
