The upper layer of the skin is called the 'epidermis'. In birds, it contains no nerve cells, and their Merkel cells are located in the dermis. However, in most animals it contains a scattering of nerve cells called Merkel cells, located at the basal layer.
The middle layer of the skin is called the 'dermis.' It contins blood vessels, most of the nerve cells, and other structures.
The lower layer of the skin is called the 'sub-cutis' and mostly contains fat.
