Feeders: make sure you get one with a brim so when it rains your feed doesn't get all wet (bad for grain but particularly bad for pellets). We don't use the step on types, I don't mind feeding wildlife, don't know how chicks would learn to use them either.
Water: if you put it in tubs or bowls be careful as wild birds and hen's chicks can get in and drown (we have made this mistake - twice). They drink everywhere as previous has said so probably a few shallow dishes around the place best and fill with rainwater. If you do buy one make sure it's galvanised and won't go rusty, you don't want rust in the water especially if you put in a slosh of cider vinegar for their gut.
Don't buy the plastic type feeders or drinkers - they blow away in the wind when they're empty, useless.
