i use a owl on top of loft and i know you will all say it dosent work, but i havent had any attacks since
i put it on roof ov loft. yet other fancyers on allotments have had trouble with hawks, and i tell them
to get one ov theys owls they just give me a funny look at £5 quid and no attacks they can look all they like
p s my birds go out as much as possible
