Its hard to tell in the picture but the chick on the left is much lighter then the one on the right. also look how much longer the wing feathers are on the right chick. What about this guy I think he is produced by my BCM roo and BR hen would he be a sex link he sure has the white dot and looks like barred feathering, thought just one of my BSL untill I saw the Feathers on his legs Boy or could it be a hen?.
