I had a good few days hunting over Christmas
and had the exact same ingredients.

Gently fry off a large chopped onion until soft and yellow. Reserve.
Dust meat in seasoned flour.
Fry off the venison and layer in the bottom of a deep pie dish.
Add a layer of onion.
Fry off the duck and pheasant.
Layer into the pie dish.
Add rest of onion, chopped mushrooms, parsley and a boquet garni.
Cover with some brown stock.

You may need to add some cornflour in cold water to thicken.

Cover lightly with foil and place in oven 180 deg C for 1 1/2 - 2 hours.
Remove and leave to cool.
Add pastry, brush over with egg and put back in oven until golden.
