The cream legbars were developed in the 1930-1940's as production birds. The researchers started the project with and english strain of brown leghorns that they had kept in their research lab for many years. Since the goal was high product, the second year they introduced a high production strain of Dutch brown leghorns that they imported from the Netherlands. The English strain introduced a light ground color chipmounk patterns and the Dutch strain introduced a dark ground color chick down pattern. Both are present in the currently legbar population. Additionally the Legbar was often outcrossed to brown leghorns (and other breeds) to create new blood lines, hybird layers, etc. I have seen about a dozen different chick down patterns in the closed flock of Legbars that I have been working with since 2011. Yes, I have seen legbars this dark. The ones I saw were overmelonized resulting in black crests, black lacing on the breast and body feathers, etc. These don't look like oilve eggers to me. Olive eggers would be a hybird of a blue egg layer and another breed. The other breed is ussually not barred so all the offspring come out with just one barring gene so they all have the appearance of a pullet when compared to autosexing Legbar. What I see here are double barred males. That only results from a two barred parents.
