My mean girl was not moving much when I went out this afternoon. I picked her up and flipped her over to check her vent and she had what looked like yolk dripping out. To better check her I brought her in and gave her an epsom salt warm water soak. I feel nothing to indicate that she has a bound egg her abdomen is soft but she was not herself. I noticed she drank more today than usual but the day was a bit warmer than it has been in a while. She is eating well, pooping and drinking her water. She was just not moving when I went out and that is really not in her character I even gave her some scratch and she only ate what fell in front of her. Checked her feet to see if she had a thorn or something stuck in one of them but she was good. I dried her with the blow dryer before taking her back out. She really seemed to enjoy the heat from the dryer, she closed her eyes and calmed. I put extra hay down for her where she sleeps before putting her in. She did come out and run around her yard a bit and drank more water before going back in. She is in her own area due to her aggressive behavior with the other hens, so it is easy to tell how much she is drinking/eating. She drank a little more than half a bottle of water, I fill her bowl in the morning with warm water from a regular size water bottle. Any ideas?
