I walked into my coop and my rooster was beating the snot out of one of my hens. Definatly not the mating dance...he was holding her down literally peeking and ripping her feathers out. I shoo'd him away and as soon as she twitch he was back at her tearing her apart. I shoo'd him away again and I'd thought he killed her because she was laying on her side lifeless. I picked her up and she weakly clucked. As I was carring her out I noticed another hen laying "dead" in the bottom of the coop. Totally lifeless...I thought for sure she was dead. I touched her and she opened her eyes but didn't move. I picked her up and notice she was skin and bones. I immediatly rushed her indoors, cleaned her up and offered her some food/treats. She couldn't even stand and she didn't want the treats so put her in a kennel in my kitchen and after an hour she started trying to stand up. She ate like there was no tomorrow though she was very wobbly. She was fine yesterday...in fact she was the first one out in the run yesterday. These two hens are the smallest of my flock. They all have been living together and the roo is only 7 months old. Why was he starving and trying to kill these two girls?
