She has laid a couple of eggs with blood on them but yesterday it was really bad and we noticed she had lost lots of feathers around her vent and her back feathers were filthy and gross. I thought maybe she was prolapsed until I rinsed her. I am new to having egg laying hens and have NO IDEA about them when it comes to stuff being wrong. A friend with hens says she is pretty sure she has worms. Can anyone help? I want to treat her correctly. Another one has been losing a lot of feathers and I assumed she was molting for the first time, since nothing else seems off with her, but this same friend said she probably actually has worms too.
