Hello first time raising chickens. I have a hen who mated with my rooster for the first time and layed 3 fertile eggs. I put them in an incubator day 11.i know this is a big mistake, I thought she would go broody and I had trouble getting an incubator where I am. Its day 18 today and I candled and there was almost 0 development, only slight veins and a dark spot. I decided to crack them open to learn about what went wrong. Well one of them only had eyes and a tiny heart that was beating. 1 was complete dud and the other wasnt fertile at all. Did that one with a heart beat stand a chance? Did I make a terrible mistake? Oof. First time doing any of this and I've been learning on the fly.
