ok so i was wanting to further populate my coop, i was up to 10 eggs in a nest box and was expecting a hen to go broody any day. well this morning i checked the coop and the heat lamp was shot and the coop temp gauge went down to 28F! if the eggs froze are they still viable? or should i just eat them? i guess there is a chance that a hen could have sat on them to keep them warm over night. i need help guys i don't want to eat viable eggs!
