Thank you for your comments, Yes the poultry netting is electrified but we are only switching it on when they fancy chewing it or when they think about looking for a gap! Luckily for us at least one of us is here during the day to keep an eye on them, the fence will be switched on overnight to stop anything getting in or out.
They seem very contented so far, we are sure we will understand what the different noises they make mean over time.
Regards
Robert & Sarah.
