welsummers are not autosexing but they are based on wildtype thats why they hatch like with chipmunk stripes, there are other autosexing breeds that are based on wildtype too like the rhodebarWell, after I aced your little quiz, I went and looked at my three in the brooder to see how the stripe on the back of my male matched up with yours. I was pleased to be able to tell that he also has the thick dark stripe down the middle of the back, and no outer thin black stripes. He has the more smudgy looking back. I'm often mixing him up with my lightest female, because they are the same shade, and they are getting wing feathers that mostly cover up their backs now. But when I parted her wings, I could see very well that she has the middle stripe, the white on the sides of that, and then the two thin dark stripes on the sides of the white.
So it was nice to have some "book learning", and then also be able to test it out in real life.
OK, now, do all autosexing breeds have the head spot on males and the well defined chipmunk stripes on the back of the females? I'm thinking of Welsummers. They must be similar in pattern, right? Those are the only two autosexing breeds I know of so far.
