my thinking on this is send as many as you like you only need one to win the race, take yesterday we were 2nd & 4th out of 400 birds we sent 16birds the winner sent 54 he only needed one and he got it, my opinion is ya pay yourt money you take your chance, but numbers do give you a bigger chance of getting one, but we would rather be selective in our sending least you have better chance to get the right bird and less birds mean tame birds and have indvidual time for them with a smaller number of birds, also the feeding bill must be immense, for these fanciers and how often do these mob flyers get the pool money.
