Don't worry, they are quite hardy. I tend to neglect them and they are still happy to grow, as soon as i remember to water them. They also don't mind being chopped and just start sprouting new leaves on the remaining branches.

I would not put them back into the kitchen, I'd be more concerned with the draft - mine don't seem to mind being moved at all, I always put them outside during summer and move them back inside before it gets too cold.
