one of the main reasons why young birds are lost, there bred early december, january time, and there trained at 6months old. They might home but they dont have the same intelligance as the later bred youngsters that you breed in your 3rd rounds, as these are pushed to get into the races. A little darkness tip if you want to practice the darkness when you take them off the dark leave your lights in the loft till 10pm, all youngbird season, this way your ybs shouldnt drop a feather and should hold a full wing the whole programme!
