What you need

DRY SPOT, at ground level on a bank or along a fence line/hedge, within flower beds or shrubs, out of direct sunlight (dappled is ok), close to lots of flowers.

TERRACOTTA FLOWERPOT, 20cm+ in diameter, sitting in a shallow trench. HOSEPIPE, great than 18mm diameter, 30-50cm long, 5mm holes skewered into the bottom to allow water to drain out.

FLOWERPOT TRAY or tile to protect from rain, sitting on stones to allow airflow.

CHICKEN WIRE, fashioned into a square cradle with the sides bent down and under, so the nest sits above the soil and stays dry.

NEST MATERIAL, ideally from existing mouse or rabbit nest, and/or moss seeded with rodent poo.
