Of course they do! For drinking from. My chick brooder started out with the standard water dish, but the girls made a complete mess of it. By the afternoon, it was full of shaving and poop and a big annoyance to clean and change so frequently. So I hung up this handy little waterer, called a chicken nipple waterer. Kind of a similar idea to those water bottles hamsters drink from. I showed it to each of the chicks by holding them near it and dripping a little water on the tips of their beaks. I was worried they wouldn’t be able to figure it out and we’d have a bunch of dehydrated little peepers by the morning, but they all figured it out with a few minutes! I’m such a proud chick mama.
