Never bred beardeds before...but from what I have seen of breeder setups, basically a row of tubs, either rubbermaid or sterlite 55l tubs with long shop light fixtures, the 4 foot ones typically, with uvb bulbs, so they cover three to four tubs and standard clamp on lamps for heat. Anywhere between 5-15 dragons per tub...less for older ones of course.
Nips can happen even accidentally as they are chasing crickets etc..and a tail or toe gets in the way. But constant feeding, 3-5 times a day for the first 4-6 weeks and fresh greens available usually minimizes this. Separating bigger guys regularly so they don't end up dominating the smaller ones is a good idea too.
