Last summer, I got a 2 year old barred rock hen. I think she may have laid one or two normal eggs when we first got her, but she also laid a lot of wind eggs at that time, and since last summer, I could be wrong, but I don't think she has laid any normal eggs. They are all wind eggs that I know of. Recently, the problem has gotten worse. She is still laying 1-2 "normal" wind eggs per week, but this past weekend, I saw her lay this deformed monstrosity:

It's the kidney-shaped thing in the middle of the photo. She was about to lay it in the nest box but then I guess she changed her mind. All the chickens then fought to be the one to eat it. Oy!
I have been getting some messy, eggy nest boxes lately, and this is probably a big reason why, but it may also partially be due to a pullet that I have who sometimes lays shelless eggs.
Anyway, does anyone have an idea of why my barred rock would be laying solely wind eggs? Is there anything I can do to fix it? I am afraid my chickens are going to learn to be egg eaters, at this rate.
