I have been sadly disillusioned with trying to train and race a small team o young birds ,the old birds lost a few ,had one or 2 killed before my eyes in neighbours garden and a couple me and wife saved but all in all old doos i found enjoyment racing etc ,on the other hand youngsters to put in the effort of training suffering losses ,and then eventualy getting some to 1st race ,then on to race 2, your team desimated by hawk,poor weather pressure (thundry clouds and atmospherics) what ever,, is to stressfull and not worth the bother from now on nae racing youngster just private training and leaving them to mature ,is the doos worth still having oh yes ,we have to change to over come our own probs and i dont know the answer to the overall slaughter of youngsters except what i am trying myself
