Thank you very much guys for lessening my worries.I guess I better give her a week or two to settle in her new environment. My worry started when I weighed her because I got 3 September hatchlings which are all weighing at least 220g each, which are almost triple her size.
I tried offering her a live small hopper this morning, but then again she just doesn't showed any interest. She's just getting stressed out. So I just returned her to the enclosure.
Here's her current set-up:
She usually burrows like my mojave. My mojave usually prefers eating freshly-killed and in complete darkness. Other than that, she also won't eat. But she's a healthy 206g, unlike my BEL.
Temperature doesn't seem to be a problem here in the Philippines as the average temperature in my reptile room is this:
The breeder told me she ate a hopper mouse last Thursday, and just shifted from pinkies.
