Yes, a certain amount of moping after a move is normal. As long as they are still eating and drinking, don't worry about it. They'll settle in in a few days.
Did the coop come with the chickens? If not, keep them shut in it and don't let them out for at least three days - they need to learn where "home" is so that they find their way back to it when they do go out.
How old are they - I'm assuming full grown? Hens, roosters or some of each?
They need water. A plastic bucket is OK, try to get one that's about chicken-head-height. Won't hurt them if they have to stretch a little to get a drink, and the taller and heavier it is the less likely they are to knock it over or scratch food and straw into it. The water should be changed every day. In winter you'll need to go down first thing in the morning and break the ice off it, top it up with hot water. I also used to feed them a hot breakfast on winter mornings (just their regular food with a bit of hot water poured over it, like a sort of chicken porridge - they go nuts for it.)
Food - I second the recommendation to get some more pellety stuff if you can. Don't know what's available here though. They also need some grit (e.g. ground oyster shells) or small stones like you'd put in an aquarium. You can just scatter a couple handfuls of this around their yard, they'll find it and pick it up as they need it.
They will eat all sorts of kitchen scraps - well, almost all sorts. Mine hated bananas. They'd take an experimental peck and immediately start wiping their beaks on the side of my shoe(!) trying to get rid of the nasty stuff. But potato peelings, onion tops and tails, anything like that... also meat scraps. And they will
love stale bread. Feed it to them by hand and you've got a friend for life.
If you have hens they need a place to lay their eggs. A good nesting box should be big enough for the hen to turn around in but not much larger. It should be up off the floor (maybe a foot off the floor) and open in front, closed on top, back and sides. Put some straw or wood chips in it, which they can then arrange to their satisfaction. One nesting box is enough for four or five hens. They'll probably find it and start using it on their own, but if you do keep finding eggs in odd places, pick them up and put them in the nesting box. This time of year, an extra day or two won't hurt them (eggs will keep at room temperature for several weeks) and the hens will start laying there once they see other eggs there.
Oh, and they need to be shut in at night - summer
and winter - to keep them safe from foxes, neighborhood cats, etc. They'll go in by themselves around dusk, you just need to count heads and shut the door. If one or two are hanging around outside you can gently chivvy them in.
I'm so jealous.

Have fun!
