We have a buff orp hen who has been acting strangely. For about a week she has been distant from the flock. She has been laying for about 2-3 weeks. The last few days, in the morning when they are let out to free range, instead of running out as fast as possible, she sticks around inside the coop. I assumed shes just sticking around to lay her egg. Today, she stayed in the coop a very long time. After laying an egg, she completely disappeared for several hours. Now that its getting dark, the whole flock went up to the coop, and she stuck around our house. I took her up to the coop and she refused to go in, just jumped on top. She got in a bit of a scuffle with our alpha rooster when I took her up there. We have 5 hens and 2 roosters. I know that is not an ideal ratio but they get along well, there is minimal hen harassment, and they all have ample space to get away from each other. They have a 24/7 access 16×12 run, and a roughly 8×4 coop. They free range around 2 acres for 10-12 hours almost every single day. My mother is very worried and I feel like she is fussing over something that's more like a like a teen rebellion stage. She eats and drinks and appears very healthy. Her crop and cloaca feel/look normal. Could this be a sign of anything? Should I be more concerned?
