I went out to close the coop hatch (like every night) and to my surprise I found two of my girls (the smallest) sitting on the perch in the run. They've never done that before? And last night when I went to close them in one of them was hanging out at the door sticking her head out as if she was going to come back out? Normally soon as it gets dark they go in and roost inside the coop. I've read other post about the same thing but I don't have any of the problems suggested. No mites (that I can see) They have DE in the coop. Plus two of the girls were already in ready for bed. There are no rats or anything. Nothing can get into their coop. Its like Fort Knox in there. They have fresh water and the coop is clean. As for being too hot? Well it's our winter here in Florida and the thermometer says it's 60* in there. So no mites, can't be hot, and we don't have any bullying roosters (we don't have any roosters). I had to go in and put them in. They were going to sleep on the perch in the run? So what could have happened? Should I be worried?
