If they get stressed when taken outside, should you even bother trying to acclimate them to going outside or leave them in the comfort of what they're used to? I've taken my girl out a few times and she just hunkered down in the grass or crawled back up to my neck.
If she is stressing out I would not-- if the beard is going black and shes happier in the house then I would do just that - put her in front of a LR window so she can look outside

Worth noting that I have short hair (2cm max), so it's more so being comfortable on/around me than hiding on me, but she definitely tries to hide if she's on the ground. Sadly this house doesnt have any good windows for her, so she'll mostly be stuck with artificial sunlight.
