Yesterday my husband went out to feed our girls and put them in for the night. It was pouring out and 1 of my older RIR was outside getting soaked and very slow to come in. He said it looked like she wasn't doing well... This morning when i went out, I opened the door to the run, counted the girls as they came out, 1 was missing... I opened the door to check her and she "rolled" outside. She must have been up against the door. I feared she had died, but she is still alive, breathing and she tried to flap 1 wing and fell to the ground and just put her head down and layed there in the rain. I picked her up and brought her in out of the rain and put a heating lamp on her. She is still breathing and when you talk to her, she will fidget and mover her foot or wing, occasionally will lift her head but keep her eyes closed. I know she is alive and it breaks my heart to see her like this. I'm not sure if she is just old or if something else is wrong. She has no visible signs of anything, i checked her over. Is there anything more I can do to help her?
