I had this hen for 4 weeks. She was 3-4 years old when I got her. She had had some poop sticking to her butt and feathers here and there that I picked off from time to time but it looked like it cleared up about a week ago. She was nice and fluffy and walking around and enjoying the yard. Then, I didn't really see her yesterday or today before I left for school. Then, today in the afternoon, my mom found her in the coop in the egg box, where she had been for awhile. She was straining to lay an egg for awhile. My mom helped it come out, gave her a warm bath, but afterwards she was very lethargic and wasn't moving around so she put her in a box with a heating lamp and let her rest in the coop. My mom said her vent ripped a little bit when it came out. A few hours later, I found her dead. She looks like her bum is very wet and caked after what happened. I'm just wondering if she died from passing the egg or if there is any illness I should be aware of that would cause this.
