Yesterday I was out in the coop feeding the chickens one of them was walking slowly and wobbling around. She fell and couldnt get up. I helped her eat and thought she just kept getting pushed around by the others and not able to get food. Then today I found her getting stepped on so I pick her up, and bring her into my house with water because I felt her and she had eaten. I was talking to my friend and petting the her. Then I felt a lump on her backside. I take a look and her anus is sticking out a bit. I dont know what to do and Im scared shes going to die. I have a heat lamp inside the coop for my chickens but I dont knkw what caused this to happen and I dony know how to help. Can you help me?
