For any non-white chicks from a white mama, the daddy is the black. As was said, the white is recessive white, which is an OFF switch preventing creation of feather pigment, thus no colours or patterns can appear even though the genes are present that would create various colours or patterns. It takes two recessive white genes to trigger this switch. So, when only one is present (from mama), the colours and patterns are able to express. Each of the hens can and almost certainly does have a different mix of colour and pattern genes, meaning that paired with the same cock they will produce different varieties of chicks.
All of these chicks will carry a copy of recessive white--if mated with a white half their offspring will inherit a copy from each parent, and be white. If paired with another bird split for recessive white, 25% will inherit two copies and be white, 50% will inherit one copy. However there is no way to tell white of the chicks inherit one copy versus zero copies.
