I have a Pekin hen that has been on her nest of eggs for almost 30 days or so. She only came off once or twice a day to eat and drink but she always went back. I noticed last week that she had pushed an egg or two out of her nest. This afternoon she is now where to be found, her nest is still full and there are two eggs about 8 ft from the nest with small holes in them. Anyone have any suggestions as to what could be going on?
