Thanks to the many responses I got from "what breed is this" I have a good Idea what I have now. I have three brown cornish and one ancona. Here is the question. my ancona lays white eggs. Shes' the only white egg layer at the moment. The others are a nice tanish light brown. I just made a 4 egg omelette. Two with white eggs two with tan eggs. The two tan egg yolks were MUCH MUCH deeper in color. The white eggs were still a darker yellow than store bought...but the tan ones were nearly red they were so yellowy-orange. These ladies are all fed the same. What gives?
