I have a dish of minimealworms in the cage all the time but twice a day I will hand feed them silks or hornworms. Then I put a few on leaves and stems. I have put small roaches in a dish but haven't noticed anyone going for them. Of course tiny crickets get thrown in at times also. When I use crickets I will put a piece of carrot in also for them. This seems to help keep them off the babies. I have tried to catch uneaten ones but I'm not to good at it. I found some very small earthworms in my backyard (in a pile of leaves after a rain) and put them in also. Babies weren't interested.
My first clutch couldn't get enough minimealworms but this one seems to prefer the hornworms (1st) and silks (2nd).
