If your Ameraucanas are true Ameraucanas and not the EE’s you get from the hatcheries, you should get red sex links with your Delawares. You probably will anyway but hatchery EE’s are mixes and you can’t always be sure with mixes. The Blue won’t show up at all on the down. It will show up on the feathers that would normally be black when they feather out. NOT if they are Wheaten. Wheaten just cant be use for Barring sex linksks Red sex links, not black. I was hoping you would weigh in. Nicalandia is much more experienced in this than I am.
