It's really a lot more simple than it sounds. Food, fresh water, clean bedding, and that can be just throwing some on top of the old, keep them dry, and I recommend feeding the first bag of feed medicated. Look at it like you are giving your kids their immunization shots...although this is just for cocci, or more specifically to help prevent it in the first few weeks of their lives. Mine still haven't finished the bag and they are over 3 weeks now. Try not to stress, so you can enjoy your birds. I didn't get to handle mine for 3 weeks, until I got them in their coop, as my kittie was really jealous and would eat them, so I just talked to them and sat by them...now, in their coop I can sit with them and they are flying up on me, letting me hold and pat them...they come to me when I call them...so see...no need to worry! Raising chickens is really easy once you get them through the first few days and weeks...and they grow fast, so enjoy the fuzzy while it's there...mine are pretty feathered out at a bit over 3 weeks now. Like NC Chick Man82 said, decide if you want to vaccinate for mareks, as you are supposed to do it at day one...or as soon as you get them. Probiotics are really good all round vitamins and minerals, but vitamins can make the medication for cocci not work, so don't use if you are feeding medicated feed for the first bag! If you aren't, no harm in using it!
Take a big breath in and let it out, and enjoy your new flock when they arrive, the journey is the fun part!
