I’m not a professional, but your care looks fine. To me, it sounds like the stress of a new environment may have triggered a brumation.

However, I would take them to the vet asap. It’s been long enough to be concerned. Reptiles are very hardy, but that often means they can suffer for a long time before signs show. If they are sick, they probably have been for some time and it may be dire. I wouldn’t count on it, but the vet should be your next step.
