I hold them every now and then to get them accustomed to handling so it would be easier to handle them in the future, but one of them jumped from my hand as I was going to put it back into the brooder box and fell about four feet down onto hardwood floor. It used to be the fastest chick in the box, but now it doesn't want to put weight on it's right leg and just lays in the straw. I picked it up again, closer to the ground this time, and held it's body between my thumb and forefinger and moved it forward to get it to move it's legs around like it's walking. It worked, and it seems like it has it's full range of motion in it's leg still but won't put weight on it. Do I need to just leave it alone and let it sleep in the brooder box or do I need to help it?
