Quote: Has she always had problems laying these funky eggs or did it just start?
Are the other birds laying OK?
Are they the same breed from the same place?
Not sure about your mix of foods, but if the other birds are laying OK,
then it could just be this one birds inability to process nutrition or something else genetically wrong with her reproductive system.
I like to recommend restricting the diet to only a well balanced chicken ration for a few weeks just to rule out a nutrition imbalance.
