I'll never know which egg belongs to which hen because I have my Silkies and Cochins mixed together. But, I can at least try to solve the mystery of a long oval shaped white egg I found a couple of days ago. And today I found an off white egg with slight blood streaks on it. So I'm thinking my 6 month old blue Silkie or my 7 month old partridge Cochin has started laying. Or maybe both!They are between an off white to light brown. Each of my hens lays a different shade. I have one bantam wyandotte in there and when I see a darker egg I know it is hers. No dumn questions can be asked.
Well my LF cochins lay medium brown eggs but my silver laced bantam eggs are nearly white. Thats just my experienece.Ok, I feel extremely stupid asking this question but what color eggs do Cochin bantams really lay? Breed standard says brown but when I do a search on Google, I also find white eggs that are claimed to be Cochin eggs?
How much do the egg colors vary?
My silkies lay the longer oval ones and my cochins lay the roundish ones. I must say the roundish ones arent much when they are pullets. 
Must be that both my pullets have started laying at the same time.My silkies lay the longer oval ones and my cochins lay the roundish ones. I must say the roundish ones arent much when they are pullets.
