What will my chicks look like as adults?

[PippinTheChicken]

Based on the pics of my chicks, does anyone know the genders, colours or comb-style of my chicks? OR ANYTHING ELSE!
They are 4 weeks old. I wanted to know the colours because one of my chicks is growing a mohawk with black spots on it and I am very confused since the others aren't doing this. I will attach the photos separately with numbers.

They look like silkie / polish crosses. I have no ideas as to what they will look like or what their genders are.
