I went out to lock my chickens up this evening and count them as I do each night. I have seven and only counted six. One of the SLWs was missing. I looked in throughout the front windows of the coop with a flashlight and I couldn't see her anywhere. It occurred to me to lift the egg access door and see if she was in a nest box. She wasn't, but she was on the floor of the coop nestled up against the hardware cloth of two nest boxes that are closed off. She woke up and looked at me, but seemed to want to stay where she was. I decided to leave her till morning. Should I be worried? Or go back out to the coop and get her out and check her over? None of my girls have ever slept on the floor. It seems like it might be because something is wrong. Any suggestions?
