You also need to remove dead ones as soon as you see them. They are cannibalistic so if they start eating dead and dying ones they can end up dying sooner. Provide a lot of hiding spots for them. Crowding leads to more cannibalism.
Like the people before me I like dubias waaaaaaay better and they don't require a lot of cleaning since they don't make a big mess and don't need as much space compared to grasshoppers and crickets.
They are also more nutritious than crickets so they would make a more ideal base feeder.
My dubias get breeder pallets and dubia flower/porridge (protein, fibers, calcium, magnesium and essential amino acids), additional I put in any fruits or vegetables we have available and sometimes the crested gecko jelly they seem to enjoy a lot.
Crickets I just get from the petstore every week, then feed them some apple or w/e is available powdered with some gutload supplement I've got to give their nutritious value a boost. Sometimes I have next to none die, other times a lot of em do... It depends on the batch since I get them from the same store every time that has had the same supplier for years..
I hate crickets, it's the big downside of the hobby to me and I still hope my Jacksonii finally starts choosing dubia's over crickets so I can cut waaaaay back on those annoying little @!$#^&^%&$
Im with you you can buy big bundles of fresh mustard greens and collard greens for really cheap at the supermarket crickets and about any feeder will love them that combined with some good dry food is all you need.
