I'm an IT pro too, and genetics has fascinated me for decades, yet chicken genetics I found more complicated than the others I've studied. I can finally now say I thoroughly understand the regular "commercial" sex link chicks (red, black, and feathering), but chick down has so many variables that it seems far more complicated. I lurk on the Rhodebar thread and read any threads I find on barring, and now I think I get most of it. Others here have helped a lot, so I like to pass along help when I can to pay it forward like they did.I am a computer programmer. Have been for almost 30 years. I had to clarify that I am not totally incompetent, before I say that the Chicken Calculator left me dumbfounded. I've bought 2 books on chicken genetics, but obviously it just hasn't clicked for me.
This is frustrating, because I really want to understand this.
