after a day or so or when they have completely dried off and got that easter egg fluffy lookk to them lol, get your brooder box switched on now so the temp is pre heated for them to go in, chick crumbs put in egg cartons, as they will make a hell of a mess when they feed, shit and all sorts in it, just pick, throw away and put the other half of the egg box in, chep, safe and above all else, hygienic for the chicks.
Best of luck with them
