For the first week I put soluble vitamins in the water to give them a boost, it really helps. You will need feeders that give good access to the feed but keeps feces out for the most part. The feed store will sell chick starter. Put that in front of them as soon as they arrive. Leave them on starter until 8 weeks of age, you can get it medicated or not.
Some people swear by medicated starter and others swear at people who use it.
The choice is yours. If you don't use medicated stater be sure to keep the tub clean and especially dry. You will find that the paper gets wet around the water cans, it is this dampness that can breed coccidiosis which can kill your birds. Sometimes infestation can be so high that even medicated feed is not enough. So keep the area clean and dry and you will likely not have a problem.
