Are you outside the US? They really don't look like any standard breeds, I'm thinking mixed. I see a hen that looks like she's bred to be a layer and tolerate a hot environment, a mature rooster and a young rooster.
The rooster could be an easter egger but its hard to tell cus the pictures are very bright and out of focus. Do you have a close up of the face of the rooster? They have very big combs so maybe they are leghorn crossed or something. sorry im no professional but thought i would guess
