Some interesting points ! Are you saying that only the birds that home on the day (500+) have had a drink and only eaten the correct amount and the rest fall ? Can't buy that , don't think we give credit where credit is due to the convoyers , and how do we know that the first birds home are,nt the one,s who gorge themselves in the basket and out last the others home ? We don't . A good bird will get home but del is correct in that fill them full of fats at right time and you have done your job then let the birds ability come through. Jmo
