not lost many, as taking it easy, especially on first race & training, why rush the youngsters? as (in my opinion) & listening to well experienced flyers, there is too many breeding too many birds & crossing there fingers. a few in our club sent 11 birds & more, & have more than half missing? there is time for 2nd 3rd & 4th races & this is even before they are mature birds, 2 yrs, 3yrs etc.
only my opinion.
thanks
