We have 2-10 mo old beardies who are special needs, I guess you'd say. They were housed together with a bunch of babies at a pet shop; Issy is missing more than 1/2 her tail and Rubio is missing fingers and toes. It took awhile after bringing them home to get them healthy, but we did and they're both doing well. We have 5 beardies and they're all housed separately. We tried recently to introduce our two youngest beardies, I was right beside them, they both started attacking each other but snout pushes, big beards and rushing at each other, so back to being separate. I'd recommend you house them separately, they can cause major damage to each other, and very quickly, when you least expect it. Hope this helps your decision.
Good luck with your littles ones, beardies are so easy to love!
