Hello, I used to be a member but lost my login and have returned since I just move to the country and can finally have roosters. I have had chickens most my life, but in the city my desire to hatch chicks was limited to ordering eggs and incubating, and to a smuggled Serama rooster in my basement. But I have delved quite deeply into pigeons, and am especially interested in genetics in poultry. After learning pigeon genetics, chicken genetics seems relatively easy, but still is one of the most fascinating aspects of the hobby. I am especially interested in the genetics of autosexing because it is incredibly interesting and useful for selling chicks locally. I also am a fan of all the "extra" genes in chickens, crests, leg feather, and especially beards. If I could have every bird I keep have a beard on it that would be fine with me! I am starting to think about my breeding goals, and I plan to do a couple autosexing projects in the next few years, starting with an autosexing EE project, using Legbars, Ameraucanas, and Bielefelders. Besides being autosexing and laying blue/green eggs, the goal is a calm/personable chicken that lays well, is beefier than most EEs, bearded, crested, and pea combed. I also have some other projects floating around in my head, so I was just curious and have a few questions. I know that sex-linked barring is usually a key component, but are there any of the other sex lined genes (like Chocolate) that can produce autosexing birds that breed true? And for traditional barred sexlinks, what base colors can work? I know wildtype and partridge do, and wheaton does not since wheaton chicks are yellow. I assume it would also not work on black or birchen? What about modifying genes? I'm guessing a gene like mottle would not effect it since it doesn't show on chick down. Are there any modifying genes that are incompatible with autosexing? For example, would two doses of Blue dilute a chicken enough to make sexing impossible? I assume Lavendar would also dilute a chicken too much to be sexable? What about genes like Colombian, Darkbrown, Laced, Melanotic, Charcoal, Mahogany, Dilute, Cream (either ig or Cb), Silver, or any of the I series genes? Alot of questions I know, so thanks in advance!
