I have a hen who's been broody for a bit setting on wooden eggs. I got a dozen fertilized eggs from a friend, and she's been setting those. For some reason, today she moved to another nest, with both wooden & unfertilized eggs. I suspect that when she got up to eat, one of the other hens got on the nest to lay, and when mama came back, she just went to another nest with eggs in it. I moved her back to her nest when I found her. I was not home when this happened, but she usually gets up between noon & 1:00 to eat. I found the eggs, which were cool but not cold, about 7:00, so depending on how long another hen sat there, they went from 5 to 7 hours without a hen. It was 75', and the nesting boxes are on the west side of the henhouse. Given all this, what are the odds the eggs are still alive?
