I have a broody who has been sitting 10 eggs for a week. Apparently she got off to feed and returned to the wrong nest box where my other (non-broody)girls laid their daily eggs. The 10 are now cold, like close to fridge cold. She was on them last night, but I don't know what time she got off of them today. Can they still hatch or is it useless? If I put them back under her tonight? They are currently warming up on my kitchen counter wrapped in a towel.
