One of my Marans hens has been waddling around like a duck for six weeks. When she first started, i didn't feel an egg or anything in her abdomen. She did have a few lice which we treated with seven dust. She has lost all her feathers on her bottom and belly but that's probably because she drags around on the ground. She is eating and drinking and moving around fine. Well, as fine as she can waddling. I don't want to do a treatment that will hurt her (like poke around in her for an egg). I have given her warm baths occasionally and will do another one today. Any thoughts? What on earth is wrong with her? Eyes look bright. She seems fine except for her walking. I don't think she's laying but I have a lot of chickens so I'm not sure. Haven't seen her in a nest box.
