Never got on well with poultry netting, lots of potential for grounding and very long in wire terms so needs a hefty energiser to give a decent shock.
If it going to be (semi)permanent I use 2 methods for poultry with success to date (tempting fate):
1. Wires (polywire) at 15cm, 30cm, 45cm, 60cm and 80cm.
2. 4ft chicken wire (non electric) with a run of electric polywire on the outside at 15 cm and 5cm or so bellow the top (seems to be a popular method with gamekeepers for poult pens).
Proper wooden braced corner posts keep it all taught.
Remember to keep vegitation off the wire, makes a real difference to the jolt delivered.
