I hope that you have a better hatch this time. Those dog's of your's are going to like that meat off of any boy's. Don't let them see you cull them when it's time. You don't want them to think it's ok to do it if you did.It's Day 8 and I just candled the eggs. There are 21 eggs in the incubator, which is about a week's worth of eggs from the 3 Leghorn hens. Out of those, 7 had something in them, and 3 of those 7 were iffy. They may be blood lines rather than veins. One of the 4 that remain if you don't count the iffy ones has two dark spots with veins coming out of those spots. That egg might be a double yolk one. The girls started out laying lots of double yolked eggs, but lately they've pretty much gotten away from that. They still do one sometimes. So 3 are looking good.
