Please help me. My oldest chicken is named Ethel, and for quite a few months, she has had a very swollen and hard abdomen. Today, I noticed that she wasn't pooping very well. It appeared to be that she is constipated. Ethel is 5 years old, and my sweet "Old Lady Ethel". I know she is older, but I would like to atleast know why she is this way. She is very alert, and likes to talk to me in my mornings before school. She doesn't lay eggs anymore.
