You've given out a little more information. I'm still not totally sure I know your goals with roosters or why you want another, but it sounds like it is not for fertilizing eggs. I agree with the others, if you can't handle extra roosters you don't need to be hatching. You never know how many will hatch or how many of either sex you will get. Very few of my hatches actually split 50-50. Most are in the range of 2/3 or 3/4 one sex or the other and that's hatching around 20 chicks at a time.
If the reason you want a rooster is that you like roosters, you may have other options. You may not like these options but I'll still mention some.
You can divide your coop/run into two sections or build additional facilities and bring in a mature rooster after your pullets become hens. Keep two separate flocks. The potential downside of this is that you may have biosecurity issues. It's always possible that you could bring in a disease or parasites with a new chicken. Lots of people do this and never have issues. A proper quarantine can help, but it's always possible you could introduce something. That's why I personally only bring in new chickens by hatching them myself or buy directly from an established hatchery. The risk of getting chicks from a feed store is pretty low so that's an option, but not as low as hatching your eggs or getting chicks straight from a hatchery.
Then there is the issue of what do you do with a chicken that quarantine shows to be sick. Do you try to pass a sick chicken off to someone else or do you kill him yourself? You need a plan for contingencies.
Hatcheries are not going to sell just one chick. Most have a minimum order of 15, some even 25, so they can keep each other warm while in shipping. There are a few, like MyPetChicken or Cackle, that will ship fewer, sometimes as few as three if your post office is a regional center. For most of us that minimum number is higher. They put artificial heat in with the chicks to keep them warm. Feed stores often have a minimum of six chicks. That's an attempt to avoid cruelty to animals.
One way to get around this minimum number is find a buddy to split an order with you. You might find a neighbor on the Kentucky state thread in the "Where am I? Where are you!" section of this forum. Hatcheries will often mark certain chicks in an order if you ask them, usually by putting a dot of food coloring on the head.
It is challenging to raise just one chick by itself. They are social animals and really need company to do well. You may want a couple of pullets to raise with your cockerel. Another option would be to get several males and raise them together. Instead of creating two different flocks with a rooster and hens, create a bachelor pad. If cockerels and roosters don't have females to fight over they usually can be kept together quite peacefully. They are still going to set up a pecking order but a flock of all hens will do that too. Often it's not that bad.
I'll mention these options but encourage you to not use any of them. When you deal with living animals you sometimes have to deal with dead animals, whether that is dogs, cats, goldfish, or chickens. I'm not sure how well you can handle that. Sometimes an animal is suffering so much it is a mercy to put it out of its pain. It's cruel to let it suffer. But mostly chickens can be bullies. They can treat each other brutally. The more you crowd them the more likely that kind of behavior is. That behavior often shows up when you integrate new chickens. If what you have now is working for you, don't push it.
