ive just started back with pigeons as my husband passed away 2 years ago and I did help him a lot with them and missed having to see to them and train them. I have a friend of his to help Hoppe this helps who hasnt raced for over 25 years so I've been training them to the whistle If they do go on the roof which only the very young ones do now all I have to do is blow the whistle and they come down. I always blow it to get them in and feed them. It doesnt take them long to learn, it was something my husband always did.
