I have one hen that lays an egg with no shell. Everyday like clock work, she sits does her thing and hoots and hollars so proud but when I reach my hand to get it, goo is all I get. There is plenty of layer, corn, oyster shells, meat scraps,greens, even a loaf of multi grain bread given everyday. All of the other hens lay fine. Is there anything I can do or is she going to be like this forever?
