I would be interested in buying locusts if anyone is breeding them. I used to buy the large African Migratory Locusts that were bred by several people up until a few years ago. Fully grown adults are too big for most lizards, but great for frilled dragons, bearded and water dragons. My frilled dragons loved them. My sources for these have stopped breeding them now for over 2 years.
They are difficult to look after evidently and appear to have a natural die off trigger when conditions are not optimum. I am told they do not suffer neglect at all like woodies and need a lot of attention to keep going. I would love to have them available as a dietary item for my larger dragons but just don't have the time to try and raise a colony myself. I am sure there would be others who would buy locusts regularly, that might make this sort of breeding enterprise work.
