The white wing feather on the chick that I think is the Australorp, is actually turning black. Just the tip is white now.
I think the chick in the last picture is a silver laced wyandotte. I've compared them to many pics, and I might be wrong, but I know that is one of the chicks they carry. The ones I have do have the 2 thin stripes down their back and they don't have black beaks and legs.
The middle chick is partridge color, absolutely no white on their wings and that is the only one I'm really unsure about now. I've looked up some pictures of the chicks that have been suggested, but I just can't be sure. Whatever they happen to be, they are so sweet, I'm sure I will enjoy having them around.
Thanks for all the help
