Roast dinner (chicken), how long can I keep it warm for in oven?

[shadypines]

I would cover it over and have it on the 'just keeping warm' setting but what is the max amount of time I can do this for do you think?

It will dry out if you do that beyond half an hour.

Agree, it will dry out.

If you wrap it in tinfoil and leave it in a warm place in the kitchen, it will stay warm for quite a long time. At least an hour or two.
