My husband found one of our layers in the yard this morning laying on her side. Her legs seem paralysed and she doesn't move her wings. Her head is still up and moving a bit but she doesn't attempt to move, eat, or drink. I didn't notice anything different with her yesterday. She is about 2 years old and we have never had any problems. My husband moved her to the security of the coop and placed her so she could drink (however she isn't). She has not moved in over 8 hours. It is hot here, 93+ degrees so I have her by the open door with a fan circulating the air for comfort. She isn't the most friendly hen, but she doesn't even try to move away if I bend to touch her. I just went out to check on her and found a very soft egg that she has passed in the last hour or so. They are in our backyard with no other animals. They free range within our fenced in area so no chance of outside predators. Please, does anyone have any ideas what is wrong with my little hen? Any ideas or things I could try to help her. I'm completely lost, this is our first illness since we got them a year ago. Thank you!
