A blackbird has built her nest, in a beach chair in our shed, we are due to move house?

we have no choice but to move next month, the blackbird has built her nest and been sitting in it, we dont think there are any eggs in it yet, but have been unable to look without disturbing her. what would be the best course of action? we dont want to disturb her, but need our things out of the shed to take with us. (we are moving to another county and have no ties to where we are at the moment so wont be coming back) any sensible help gratefully recieved
