Yes, they quite often look like that if they are internally pipped. I have candled at that stage before.
You do need to remember that if your broody hen and your incubator both started with eggs at the same time, your broody will hatch a day earlier. If you think that you may have had some incubator temps that were a little low, it will slow down incubation causing a delayed hatch, this is normal. Your broody hens have thousands of generations of genetic memory to guide them, a good broody is hard to beat. Given the opportunity, you will be successful at this and you will be able to have great hatches. Don't give up on this one yet, you know what they say about counting your chicks before they hatch...
I know it is hard the first couple of times running an incubator. You want to do it right, you want all of the eggs to develop, you want to do everything you can to make every egg hatch out perfectly. The reality is you learn from trying and that you can do more by monitoring from a little bit of a distance than you can by hoovering over the bator.
