Going through the breaking process for some birds too at the moment, all the above is 100% correct, I would also add, let them out singly at 1st, dont be surprised if some seem to disappear then return after a few hours or so, some sit out for a day or so hunger is a great master, and mostly be prepared to loose some they wont all break unfortunatly unless you get lucky. so far I have broken 5 out of 6 in the last week , one has disappeared totaly . PS as regards racing them a broken pigeon was 3rd club for me last weekend .
