Water

When your chicks are, well, chicks, you should get a small waterer (or two, depending on the amount of chicks). When they get a little older, get a larger waterer. When adults, the chickens need a large, maybe 5 gallon waterer.

Housing

You need somewhere for chickens to live. There needs to be at least 1 square foot per chicken. So the chickens don't suffocate, you should put in some sort of ventilation. My coop has 2 sides with square holes. The holes have chicken wire over them. You should also have a roost and nesting boxes.

Feeding

For chicks, you need small feeders, size depending on the amount of chicks. Some are long and can be made of plastic of metal. These are best for around 20 chicks.Others can just be round and made of metal. These would be better for up to about 5 or 6.

For adult chickens, you need a large metal container. (Sorry, I'm not sure how big they are!) They can hang from the ceiling of the coop.

As for food, for babies there is starter. For medium aged chicks, there is pellet feed. When chickens start laying, buy layer.
