Are these eggs from the same chicken???

I would say you have at least 2 laying. The colour difference between the more blue one and the other two is too much to be from the same hen in my experience.
Of the other two, in the photo they both appear to be the same hue...does that bear out in reality? One is a notably different shape, but that can happen with the first few eggs. The shape should standardise for that hen. The shape of the egg can be as identifying a factor as the colour for which hen laid it. I have some that lay really thin pointy eggs, a marans that lays a beautiful dark egg that is very round and her sister lays a slightly more oval egg that is not quite so dark. I love figuring out who laid what.
Anyway, congratulations to your girls.... they are beautiful eggs!
