3 day old chicks picking at each other

[nursejenny00]

I have 2 easter egger chicks, now 3 days old. The first day we noticed 1 had pecked a tiny sore on the others beak in between nostrils so I separated them. When they are together to socialize now, we have noticed the other is pecking and grabbing the legs of the other and pulling her over. They remain separated unless supervised, but should i be concerned? Will I ever be able to add these 2 to my flock, let alone have them be with each other?
P. S. Pecked beak is healing well
