Very easy. Dip their beaks in water as soon as they get there to get them drinking. Put down some chick starter crumbles. Get a brooder light to keep them warm.
Keep brooder clean. Keep fresh water in front of them. Feed them well. That's it!
I don't use a thermometer in my brooders, I just watch the chicks to see if they comfortable. Chicks crowded together under the light? They are cold, lower light. Chicks crowded together way away from the light? They are hot, raise the lamp some. Chicks spread out doing their own things or sleeping peacefully? Just right.
Way more fun than Sea monkeys! Keep them clean and warm food and water,I advise using bottled or real clean water though.Alot of tap water has ecsess salt and chlorine that can cause problems and make sure your chick starter food is ground up finer than grape nuts for the first week.Just like anybaby,they poop and grow.
Easy. Look at photos of brooders on this site for ideas. They need chick starter, a chick waterer (with a few marbles in the drinking area for the first week to get them to peck at the water and make sure they don't drown), some bedding and a heat light.
It's all about consistancy. Being happy to do the daily tasks required to care for them properly in exchange for the entertainement and eggs they provide. There are things you can do to make it easier like getting informed, educated, and having a plan for what to do if things go badly, and a plan for winter care. If you generally enjoy being at home puttering with small tasks, learning new things, planning for and investing in the future, you are the perfect chicken person.
