I have started to notice a few things. There is definitely a pecking order. Couple of the times they are jumping on the backs of the smaller ones and was just making sure they are ok? I have them 6 of them in a broader pretty big actually and they are mean little boogers. Will they grow out of the frantic stage? The white legs. Won't let me even touch them but the brocks are getting use to me getting into cage and letting me pet them.
