egg revolt

Last week, I found 3 eggs in the coop, the chickens didn't seem to know what they were, or how they got there and they stood around pointing at each other.  Since then, nothing, I had nearly come to the point of deciding to get some additional older chickens and go through the troublesome adjustment period so I'm wondering if it was ruse on the part of whomever is the mindreader in the flock.
They are a little past the time by which they ought to be producing.  I would not care for myself, but there are people in my house now that eat eggs on a regular basis.
These poor girls are having to put up with my reduced circumstances.  I can't afford to replace the coop heater that died last spring, so they are going to have to rely on their reputation of being winter hardy for a while.  I could maybe scare up some bales of straw and stack them around the coop for extra insulation, I know that if it were me, I'd be appreciative, I'm not very winter hardy myself.
This morning, The hens emerged into the sun followed closely by Mr. W, and Millie crouched to the ground.  He stepped over her to get to a hen who was less willing, and I thought to myself, I know relationships like that.
