The chick in the video is the one with the light spot. I wanted to get home before dark to get you some new pics, but work prevented it - the little girl doesn't have a dark spot anymore, but her coloring is a shade or two darker than the little roo.
With my Red Hill hatch - six Bielefelders were yolkers, three Bielefelder/Orpington cross were winners but two were smooshed by Blanca just days before hatching (my adopted old hen, who is a bit of a clod but still gives a huge green egg every day despite being four-plus years old). With that hatch I wondered if their Bielefelder roo was so fond of the Red Orpington that he was ignoring the Bielefelder hens.
With my Brinkhaven hatch - five Bielefelders were yolkers, one a winner; one Niederrheiner was a quitter, two winners. I had 100% fertility with the Niederrheiner eggs. Since this was my second try for the Bielefelders, I am wondering if the roos are particular about their ladies.
Last May I purchased a dozen FBCM from Mid Missouri Marans on ebay (survivalseedsowers). They sent eighteen eggs, and in an incubator we hatched six hens and six roosters, and six did not hatch. I didn't note whether they were yolkers or quitters. I kept three hens (Vanille, my melanistic mutant foster mama, and her sisters Little Foot and Copper Top). I traded the other FBCM birds for my mix of hens. The roosters were just beautiful. Vanille is not laying because of her foster chicks, and the other two are molting and look just awful. During most of the year they give me two, sometimes three eggs a week per bird. They lay beautiful dark eggs.
I think I want to sell the pair of Niederrheiners because I don't think the roo alone would be of much use to anyone. What do you think? I'm not out to make a pile of money, I just want to prevent them from being eaten (at least right away) - they are the sweetest birds and so very friendly.
I'm in Southern California.
