Every morning i feed my chameleon pin head crickets, i dust them with repto-cal and then 2-3 hours later they are dead?!!! Wtf? Why are they dying so fast?!
Since currently you do not have a Uvb source, perhaps, cup feeding your chameleon for the time being. Break off the back (shin) part of their legs and stick them in a little bowl. Your chameleon will need that D3. Maybe even just hand feed the crickets to your chameleon.
