i been doing some research on this. Basically you need to keep them light but not hungry. best way to do this give them approx 10z barley per day / pigeon. feed them 1/3 in the morning and 2/3 in the evening. Get them in condition, burn all the fat of them. Once they are conditioned and flying remember the main energy source is the breast muscle which needs fat so add some fatty seeds or grain to their diet like corn, safflower, etc. but not too much
Good Luck. or Allah kamyaab karein
Dont forget pgeons need all ingredients in balance to keep them healthy. carbohydraete,protein, fat, and vitamins
