thanks for the replies, it would be with a air-rifle and yes it would be indoors, would the basc cover the public liabilty. What it is i work in a food factory and from time to time they get feral pigeons geting inside and they have to get rid of them ASAP, they get a pest control company in, so i thought to myself i could do it and put a few quid in my pocket. i've got the tools to do the job.
