One of my female DIs goes nuts when she sees me bringing silkworms and supers to the collareds and beardies. So yesterday I dropped two supers in and she scarfed them. Today she took a silk. The other female and male don't want anything to do with the worms, so what is up with her????? Is she lacking in some way? Should I be letting her have them? She is also the first one to the salad bowl every morning.
