Glad to be of help Damien.
There are lots of ways to feed and many products to put in the water.This is just one of them.
Bottom line is Good pigeons,in good health,get them fit,educate them on the road,get a good motivational system.Unfortunately you have to do your bit and put in lots of effort.Get the above right and you won't go far wrong.
Many unsuccessful fanciers blame their birds or the ventilation in loft or anything they can think of!!! but the bottom line is that they are normally to blame,with their lack of effort.
Thats just my opinion.Best of luck with your racing mate.
