I would avoid the corn - it is know to cause niacin deficiency. Ok when they are older and not growing.Poor little babe. Was he like it when he arrived? Looks like it´s a defect, as he stands up oddly on his legs, too. And your little female...does she always hold her wing like that? If so, you may want to wrap it. As for chick crumb, etc, I leave off that at their age, except for a little as a treat to get them in, or move them, etc. Plenty of greens, a little corn would be ok, fruit, etc. is good. I see they´re on grass, and that´s just great.
