I've got 5 hens about 7 months old who just started laying. Today I discovered that one is setting a clutch of eggs in an old empty dog house we have. Here's the thing: She goes back to the coop at night and back to the eggs in the morning. Will the eggs hatch if she leaves them cold all night (here in Maine, overnight temps in teens and twenties)? Or should I just collect them when she's not looking and put them in the fridge?
