That's one very interesting subject, Trevor.
That's a very interesting reply, Andy.
A few years ago I would have been reading and nodding in agreement. Now, not so much.
Many years ago an old bloke told me that a young bird, when it was about 11 months old, or as we would call it a 'yearling', was the best it would ever be. I was doubtful.
He was probably not far wrong.
Pigeons down here fly 300, 400, 500 and more in their first season. My little Melbourne hen flew 600 miles 3 years in a row.
Most of my training tosses this year with the young birds went : Take them out, let them go, zoom home, all arrive in a rush, everyone is happy!
A few times I put the odd race bird from last year in the box, in the misplaced belief that they would help the young'ns get home. Wrong.
What happened was the youngsters came home broken up in small bunches and the old race birds came home late or the following morning. And these were only 10 mile tosses.
Then I realised that was a bad move, so I have trained the young birds on their own. Faultless.

All the old pigeons have done is head for cover every time they see a hawk.
Yes, you can race them as 2,3,4,5,6,7,8, year olds. I had a lot of old widowhood cocks back in New Zealand. But they are better and faster when they are young!
