When I raced my youngsters 'naturally' I fed Marimans Super-M. Two feeds a day, the first feed was mixed with depurative making it a 50/50 mix at around a 1/3 of an ounce per pigeon, the evening feed was 100% Super-M at around 1 ounce per pigeon. This of course had to be tweaked because the more work they put in around home plus the training they had could mean they my need a tad more. I trained them 2-3 times a week at around 35 mile (the harder they were trained the slower they moulted). I use to let them pair if they so wished which meant they didn't exercise around home too good but if I got them sitting it would slow them down in the moult. The only time they got any seed or trapping mix was when I exercised them around home before I took them training, just enough to trap them in, no seed given apart from that as again its was all about slowing the moult down. The day prior to basketing their daily ration was 3/4 ounce per pigeon of Super-M & the day of basketing they got 1/2 ounce of 50/50 (Super-M/Depurative) per pigeon. A mistake a lot of folk make is to give them too much feed on the day prior to basketing and consequentially they eat little on the day of basketing. More youngsters are lost through dehydration than anything else so giving them a half decent feed on basketing day ensures they have a good drink after they've eaten and if all is well they've had digested it all come marking.
