Where's the eggs at?

I would think you could expect one soon. Now, are you sure she has not moved her laying place? If she laid an egg with 3 yolks, it may take a few days for the yolks to move down....I don't remember just how that works. Our sex-links will lay a 2 yolker one day and then lay another egg the next.. Does she walk/look ok? Hope she did not hurt herself with a large egg.

 

Might check around the yard or in the bushes. Maybe they are hiding them??

 

She has probably started another nest somewhere. When you find the new nest, place some golf balls in it. That way she will not think something is stealing all of her eggs.
