We have one hen who persistently will develop a hidden nest - lay eggs in a specific hidey hole, but come out to free range, sleep at night on the roost etc. Then one day she will disappear. So Sunday we found her hidden nest with 8 eggs. we took them out and blocked up the area so she couldn't get back to it and kept her in the coop/run all day yesterday. Today when I let her out, she ran to where she was squeezing into her nesting area. She was making the most pitiful sounds and kept going around to try to find another way into the area all day. I gave her a cold bath and tried to distract her with meal worms and other special treats, but she was not interested. Just kept running back to the area and hung out by where she had had her nest area all day - looking sad. We don't have a roo, so no fertilized eggs. We also at this time can't add any chicks (like giving her fertilized eggs or 1 day olds to set on). My DH said that last time this happened it took a couple of days and then she forgot about it; but I feel so mean. Poor little thing!
