Where are you living and what is the temperature and humidity differential between where they came from and what they are in now? The reason why I ask is that if the plants are experiencin too much of a difference, particularly if they were just shipped, it could send them into shock. I speak from experience, having taken Neps in hanging baskets and putting them outside last summer. I had them in "bright shade" for a week and thought they were adequately acclimated. But when I moved them 3" and into direct sunlight - they fried. Two years ago I bought a cobra lily that was in a plastic cube. I don't know how long it was in the store, but when I repotted and placed outside, within hours the pitchers all withered.
What I'm getting at is that too much too fast, esepecially if in a weakened state (from neglect or shipping) can set then over the edge.
Now I just put outside buckets of minibog plants (Sarracenias, cobra lily, several sundews) that had been in a coldish attic all winter. They were in temps that ranged from the 30's to the 60's all winter, and right at a window sill. the natural photoperiod woke them up in due course and spring finally arrived in Western NY. So it was time. Now a day later, none of the plants reacted to this change. Healthy, growing plants can take some jostling.
You will know after a day of sun and fun if it was too much too fast. Generally speaking, I would put plants outside in the shade for a day and move gradually to the sunlight. Another thing to do is wait for a cloudy or a rainy day or until the sun is setting. Keep us posted!
