You are correct on the rooster. He is silver. Looks like he has some lacing which can do all sorts of things when crossed with other things.
Annette's feathers look like one of the variations of incomplete or partial lacing.
Laure has incomplete lacing. The black edge doesn't wrap around the feathers far enough to meet the black edge on the next feather, which is what makes the lacing look. Whiskey has the same thing going.
Egg size could certainly come from the father. ALL of Cheetah's offspring came from large eggs. All except 1 of the girls lay small eggs and those all the same shape
Your birds are all unique and gorgeous. And I love seeing them.
