Ill try to map this out as easy as i can.
To feed a chameleon Crickets you need:
- LIVE crickets (don't feed dead ones)
- An enclosure for your crickets
- Food/water for your crickets to eat to stay alive and provide nutrition to your cham
- phosphate free Calcium powder
- Phosphate free calcium powder WITH D3
- Multi vitamin powder
So First lets talk about the enclosure because that is where your crickets will first go after purchasing them. It's a good Idea to purchase crickets in bulk. Even if you have 1 chameleon you should purchase 250-500 in bulk from a reliable and cheap supplier. Buying 500 crickets from a store like petsmart will cost you around $50, but if your purchase it from a place like one of this websites sponsors you can get 500 crickets for around $15-25 shipped.
Enclosure: You can search the forum for proper enclosures but in a nutshell you should have around a 10gal plastic tub or aquarium with a vented lid, if your using a plastic tub, cut out a large portion of the lid and replace it with a screen. You should provide egg crates and paper towel rolls in the enclosure to provide climbing areas so the crickets have more places to move around and don't crush each other. You will need to also supply your crickets with gutload, gutload is a term meaning basically food, but not just any food, it has to be beneficial to your chameleon in the long run. You can purchase commercial gutload at pets stores or use things like fresh green veggies, carrots, potatoes ect. If you choose to gutload with things at home make sure you research to make sure what your using is appropriate gutload. The crickets will also need a supply of water, this can come in various ways. Personally i purchase this gel looking stuff and my crix love it, others use a damp sponge, this is where you need to do a little research aswell. You should clean the enclosure every 2-3 days, removing any dead crickets and removing uneaten food before it goes bad.
Supplements: As listed above you will need 3 different kinds of supplements, Calcium with D3, Calcium without D3, and a multivitamin. Personally I use the calcium WITHOUT D3, 4 times a week. I use the Calcium powder WITH D3 once a week, and i use the multivitamin ONCE a month.
actually applying the powder to the crickets can be done in many different ways, but this is how i do it:
Collect as many crickets that im going to feed from their enclosure to a small Tupperware/plastic container with a lid. Then depending on which day it is, i use the appropriate powder and just place a pinch in the container with the crickets im about to feed off. I shake the container gently making sure not to kill or injure the crickets.
From there I basically place the crickets into my Chameleons enclosure making sure the crickets don't have too much powder on them. When you apply the powder make sure there isn't so much that the crickets are a completely different colour, they should look LIGHTLY dusted before feeding them off. If the crickets happen to have a lot of powder on them just blow on the cricket lightly to remove excess powder.
And thats pretty much the feeding routine, and upkeep of crickets. Hope that helps!!
