David,
Well , you answered all your own questions. lol
They just need to adjust!
Let them beeeeeeeeeeeee in their great new enclosure you build for them!

I'm sure you know this process takes time.
Try to resist fussing with them.

If you are planning to bowl feed. Get the bowls in there now, so they get used to seeing the crickets wriggle.
They may not eat out of the bows, but they will !!!! eventually.
You will , of course have to keep the bowls really clean/refill etc.

It took my A. moreletii froglets (very young) about 2 weeks to learn to use their bowl.
I could not believe how quickly they got the hang of it.
I guess it could take longer for an older frog?
I have never had whites, however.
Don't know if their behavior using a feeding bowl is different compared to Agalychnis.

Enjoy them, they are beautiful!
