I have two free-roaming chicken that have been together since i got them (they were probably about a month old) and now they are about 6 months old.. maybe more. Just recently, I've noticed only my hen has been showing up for some food. This made me panic because I was thinking maybe someone took my rooster but during their usual sleeping time, i hear my rooster crowing away in the tree near my room. The next morning he crows again and leaves the hen alone. I feel really bad for her because she was always following him and despite his pecking, she would stay. Now it's like they got a divorce or something. Does anyone know why this is happening?
