Sue, the brown red large fowl were bred up from easter egger hatchery stock over a period of many years. The only outside blood until about five or so years ago was bantam brown red crossed with large brown red. Then I made the mistake of crossing in a black pullet. That gave me green eggs, single combs, and really didn't do what I wanted it to, which was to increase the size. This year I did not hatch a single off-color chick, but I know that some will turn out too black and some will have too much gold/orange, because that is just the way this color works. I'm fussy. I made several different lines of bantam brown reds using different outside blood over the years, but I think only one survives yet today.
