I recently moved a broody hen to place her on eggs. She was setting in a nest that was too high to hatch babies from. I was afraid that after they were born, they would fall out and get hurt.
My hen was also "mean" about me touching her so I took a rake handle and gently raised her with it to get her out of the nest. She refused to move at first, but I was persistant and it worked after a minute or two. When she flew from the nest, I moved her eggs to a lower nest out of the way where she can hopefully hatch the chicks successfully. I also removed the straw from the high nest to keep her from trying to set in it again.
After removing her from the nest and moving her eggs to a new nest for hatching, I stepped back to see what she would do. She went straight back to the nest I had removed her from and began looking for her eggs. To her surprise, the eggs and straw were gone. She had this confused look. I couldn't believe what she did next...she sat on the wood floor of the empty nest as if it had straw and eggs in it.
I moved to plan B...which is what I suggest for anyone who is trying to relocate a broody hen. I ran her out of the nest again and covered ALL nests in the coop except the one with her eggs in it. After checking out all of the nests in the coop, she went and found the nest with her eggs in it and has been on it every since. We are expecting chicks on Easter Sunday.
Good Luck!
