I had given up on my eggs in the incubator and yesterday picked up 4 chicks about two weeks old at the feed store. One was acting funny and died in the evening. Then at eleven I notice the lone egg still in the incubator was pipped. The little one hatched out about two. So here are my questions. I don't know why the chick died, how long till I can declare the others ok? Can I put my one lone baby in with the bigger chicks when they are ok? I feel like I am juggling chicks.
