a pheasant has layed a nest in my garden

hi, im in need of urgent advice, we have quite a large property, and recently have had 2 pheasants 1 male and 1 female frequently visit our property. bearing in mind we have 2 working gun dogs we were quite worried at the time however we have in fact now found a nest in our garden, with at least 12 eggs. they haven't hatched yet but were really unsure of what to do. we haven't touched the eggs but we don't know what to do if/when they hatch! any advice would be appreciated.
