Culling the all dark birds early was probably a booboo.
Culling at this age in general in a bird that changes through the first few moults (anything pencilled or laced) is going to throw out a number of what might have been good birds.
You are really jumping the gun and you will throw away good birds if you persist in over culling a large laced breed before the second adult moult.
