Well the wife doesn't know it, but I used some fake egss she bought as decorations for a jar. I think she bought them at a home goods store. You might even find them in variety type stores or 'dollar stores'..
I've found fake wood eggs in Michaels (the craft store) where their wood crafts are.
I've got 5 --3 year old hens who lay in the nesting boxes. I've got 5 new chickens (got them as chicks in April) and at least 2 of them are laying eggs. One or more is laying in the nesting boxes with the big girls. However, for the past week, I'm finding an egg in the middle of the coop, same color/size so I've got one who has decided that the middle of the coop, under the roosting area is the spot to lay an egg. This one must lay first thing in the morning as it's always there when I go out and check.
I'll try to create a nesting box out of a plastic tub and get her to lay in there, then move it closer to the nesting boxes and hope that works.
I'm getting tired of wasting these eggs as they're usually covered in poop.
If I would catch her in the act, would trying to move her into a nesting box traumatize her for life? I imagine she'd run away before I could climb into the coop.
