Hi Ryan!
It is possible she has retained sperm - but I'm not sure on the viability of the babies. It is possible they will be passed as slugs. Even among the egg bearers - viability of the eggs is reduced with retained sperm. But, hopefully.....
Werner's are said to have one clutch a year (not much research has been done on them b/c most specimens are wild caught).
I would avoid the mealworms right now as they are harder for her to digest. Keep offering her the crickets - but if she is gravid and won't eat this is normal. Keep her humidity high (especially if you're temps are high - we're going through a heat wave here) - high humidity will help prevent dehydration. But, really water her!! I've found with my veiled her water requirements are higher close to egg laying time. If the female is dehydrated - the eggs or babies may become somewhat 'sticky' and be difficult to pass. Give her water through a dripper several times a day, mist her and I would even throw her in the shower. I use a pump-garden sprayer and water them for half an hour in the tub (on a fiscus tree). I fill it with hot water - so it's warm when it gets to her.
If she's not gravid - that's another story. Most hunger strikes are due to husbandry conditions. I have a rescued veiled who was on a hunger strike from April - the end of June (so I've been there!). Re-check everything: humidity, heat, lighting, any source of stress you can think of, offer different feeders (catch some moths, flies or grasshopers from a safe place), check her hydration (they will often stop eating if their water requirements are not met), does she have lots of cover so she feels secure ... and on and on.
If she's not gravid - a vet visit is in order. Tongue problems (from under/over supplementation or injury/infection), parasites, respirtory infection, etc. Note her fecals (catch a sample in a plastic zipper bag with a damp paper towel and get it to the vet ASAP) - and the frequency.
I've got lots of tips for a seemingly healthy cham to eat - if you need them. Sorry for rambling - just trying to think of anything in this head of mine!
I'll try to do some more digging on the retained sperm thing. But, I hope it's babies!! Get those fruit fly cultures and pinheads ready!! And let us know what happens!
