Hello,
The moths don't really fly so you can keep them in a nice little clear plastic bin & just line it with paper a paper towel once you have moved the cocoons into the plastic bin. Then, let the moths emerge from the cocoons & they can mate in that container.
How is your dragon today? Well, maybe as he gets older, he wont mind trying to eat out of his tank. You could also try hand feeding him also.
