the clown next door has put stainless steel spikes in the gutters at the back of his house,to stop my birds landing on his roof and wait for it... stop them nesting in the gutters and blocking the downpipes,i thanked him and told him he has actually done me a favour as my birds wont drink out of his dirty gutters now. its not as if my birds are on open hole,they get 1 hour in the morning & night,the ybs are out for an hour and half at night,oh and he hired a scaffold to do the job.
