Welcome to BYC. Glad you decided to join our flock. Pa2chitown and Yorkshire coop have given you some good links and advice on caring for your newly hatched chicks so I'll just add, please feel free to ask any specific questions you may have. We are here to help in any way we can. Cheers.
Please offer them water only from a shallow dish, with some marbles or clean pebbles in it - to prevent drowning. Babies are not steady on their feet and also fall asleep in the blink of an eye. - sometimes falling head first into water or feed dishes.
For the first few days cover any litter or pine shavings with towel paper to keep the chicks from eating it. Once they know where their feed is, you can remove the towel paper.
