Will chickens use multiple coops??

I have one of those metal sheds they sell at Lowes and Home Depot that I'm using as a chicken coop. It works great! I have a fenced in back yard and I let my birds free range all day and they automatically go back into their coop at night. I thought about adding another shed and some more birds since I have so much room for them to free range. If I added a new metal building and birds would they know to return to their respective coops at night?
