Yes there will be a little drop of ice on the end of the nipple but when the water in the bucket hits it thaws. I keep my waterer in the coop but you could keep it out side.
There are pictures of my set up on my page.

5 gallon bucket (free), 3 nipples ($6), bird bath de-icer or aquarium heater ($15-$30.)
You can see my water system on my page. Yes we have electricity in the coop. Gets very cold here -38 last winter.
But for quick reference, 5 gallon bucket with poultry nipples, and a bird bath de-icer. We have a 130 gallon storage tank, with a stock tank heater and pump to fill the bucket.
