Sorry if this is some more gasoline over the fire:
- corncrake chicks are black, while those of pheasant are like this
- water rail eggs are not blue (they're buffish with darker spotting)
- given the number of fantastic events occurring simultaneously: corncrake nesting in Wales, then nesting in a garden (!), raising 2 broods, 1 blue egg, water rail laying blue eggs, water rail laying egg in a corncrake nest in a garden in Wales, 2 broods hatched but colour of the chicks not conclusively recorded, etc... I'd apply Occam's Razor principle and simply accept Pheasants are nesting in your garden (which is actually cool!).
On the balance of probabilities I would say an Ocean Sunfish nesting in the eaves of his house is more likely.
