It has been reasonable for a while but last night was really bad so at the moment I am pretty angry. Don't know how many are there but there is a lot going by the noise on the roof . Not sure why they want to run around on the roof so I am going to have to take action. I even thought about running electric fence wires all over it but I would need to have an earth method across the roof as well, maybe chicken wire across the roof with the fence wires just above it. I have gone through packets of rat bait over the last couple of weeks because on one side I have a woman with birds and at the rear they have chooks. I said I would win but at this stage I think they are winning. Seems like the cockatoos don't like the owls because they have only come once since the owls went up
