I am new. I met a family with chickens, thought it was great, found this website and began my obsession! I built an incubator out of a cooler as seen on the website, ordered 18 Ameraucana in Feb. and they FINALLY arrived on the 24th, only one was broken. They were over a week in transit and I am concerned they will not hatch. They have been in the bator for 8 full days now. I candled them and only one looks like it has the "spider vein" look. One is too dark to tell, one is blotchy, and the rest look like the yoke is just rolling around inside. Is that normal?
