One of my hens has never laid from the time I bought her. At first I thought that it was because of the environment change, but now we are going on six months without any sign of any intention to lay. She stands like a penguin and her duff is almost touching the ground. I think she might be in laying internally, but so far I haven't found any sort of treatment. Does anyone know anything that I can do? Or is something else wrong with her? She is a Black Copper Marans, if this is some sort of breed-related issue. Any suggestions are welcome!
