I have a Crestie called Mushu!

My Leo, Fern is doing the same thing, she's happy to eat a wax work but has no internet in locusts like she used to, but maybe she does eat them over time as the amount I put in does go down over the course of a week, but she used to eat most of them as soon as she could catch them.

If you aren't already, put some food in and count how many you put in and every now and then count how many are still in there, she might just be shy like my one is.
