There could be a lot of factors at play- not all of the eggs may have been fertilized, they could have been cracked or broken while being sat on, or there may have been a genetic issue that kept the eggs from developing. It's very common and normal to not have all eggs from a clutch hatch and produce chicks. If you are consistently having issues, or the hen seems to have trouble properly laying, you can remove the eggs and incubate them yourself using an incubator that has a better chance of stable temperature and less breakage of eggs. Making sure you have a rooster that can cover all the hens, and that all hens are on a balanced layer diet can help ensure healthier, and better chances of fertile eggs as well.
