I have 6 hens between a 1.5 and 3 years old. I let them free range during the day and coop them at night. Lucy, my favorite and one of the younger hens was fine all day, I put them up and went back to check for eggs my last time for the day and Lucy was on the floor of the coop laying down, I thought dust bathing but she couldn't seem to get up and her butt feathers were tucked down. I picked her up to take a closer look and she was not her usual self. I have looked at so much and have no idea what it is. People describe Meriks disease, splayed legs, or egg bound. I let her be a while and went back to check and she was standing at the bottom of the coop on both feet, all the rest were roosted and her butt feathers are still pointed down. Egg bound? Would Meriks come on so quickly with no symptoms? I am sick to death over this bird, I am very attached to my girls as I'm sure most of you can relate. Any thoughts?
