I personally think we should ask for there advice on how we should keep pigeons and see what they say ,They obviously know better than people who have kept birds all there lives like some members on here ,maybe they will help with the raptor problem (doubt it) I have only had birds two years got allot to learn always will learn,they have kept me sain though a tough two years .I wont let them stop me doing what i enjoy especially when i know they are wrong .
