Hello! I have a coloring question on my silkie, as pictured below. It is white with partridge though-out it in almost specks. Some of the specks are growing and covering more area. I'm wondering if as they grow they will become partridge colored? Is this something that happens, they get "speckled" like this? I have two who look like this. Also, it's a bad picture for this, but is it possible to tell if they are hens or roos? They are, at my best guess 3 month of age give or take, they are about the same size as my year and a half old hen only they were hatched this year. They have none, what so ever, appearance of combs or wattles. Thanks!
