Bucket for water unless ducklings, they need to be able to dunk their heads for keeping nares and eyes clean and healthy, feeders can vary but I wouldn't buy chicken type of feeders, rubber bowls work well something with a flat bottom so if they step into it hopefully it won't tip over so easy. I use goat troughs that hang so my flock can't climb into or knock over. shaving for their house helps keep poo off the floor and gives them something soft to lay in,. Depending on ages they can all eat the same feed but again ducklings shouldn't be fed layer. What breed are you getting and ages? and Congrats, you'll have to post pics as soon as you can. also for swimming, anything from cement rubber tub to a plastic kiddie pool works unless you have a nice pond.
