My last non-laying hen has finally started laying 

Herein lies the problem....her eggs are massive! For Silkie eggs anyway. I feel pretty bad for her :/ Just to give you an idea, here's a picture I snapped after I collected my first batch of cackle berries today:
Ok, here's what you're seeing. At the top of the pic, the first 2 eggs are what my other girls lay. All of their eggs have been about this size (except for the occasional little fart egg). My biggest then lays the smallest eggs 

 The next 3 are Lola's (in the order they were laid, Lola is my smallest hen who apparently lays my biggest eggs). That white egg at the bottom is an X-large egg from the store to show exactly how big my Silkie poos are! Will they get smaller? I can just imagine a prolapse or egg bound issue if she continues laying these!
One more problem, all of my eggs are infertile 

 Are Silkies seasonal breeders and layers? When the weather was warm, and my roo was coming into his own, he was crowing and doing the deed quite a bit. At this point he's not crowing or treading the hens at all, that I can see. I'm going to have some breakfast for dinner tonight just so I can check fertility again, but I'm having my doubts. I may also give him a trim, but I don't see how that will help if he's not interested :gah I'm seeing all of these cute chick pics and I want to incubate while my girls are laying well!
WWWWHHHHYYYY!?!?!?
