baby chicks with hurt leg

[Angerbat]

I have two baby chicks with hurt legs. I am not sure if they got hurt on the ride home or were hurt getting put in the box at the store. They are only 2-4 days old. How can I tell what is wrong? Where on the leg do I look and what do I look for. What ailments are fixable and how do I fix them? They are eating and drinking well, but I don't know how long they will last hopping on one leg.

They are both holding up the injured leg. One looks like it is hurt at the first joint or knee and it sticks out (araucana). The other one is a little more dangly and hangs under his body more (buff brahma). I will try and get some pictures today.

I will move this to the emergency section. Might be able to help more if you could describe the hurt leg more. Often chick aged leg problems are covered via splayed legs or spradle legs.Pictures would also be helpful.
