Currently have 22 chickens and 7 ducks all together. This will be the first winter with ducks and this many chickens (only had 4 chickens last year). Im in michigan so this winter we'll have many days below freezing. Im wanting to find a way to keep a decent amount of water thawed. Would be nice if i could go at least a week without having to refill. For the chickens im planning on using a 20 gallon barrel that will feed pvc pipe with horizontal nipples. Both ends of the pipe will connect to the barrel and ill have a small pump pushing the water through. Also have some type of heating element in the barrel. Seems like that will work pretty good to me. Now for the ducks im not sure exactly what to do. I dont plan on having their pond/pool available. Ive read some people will use heated dog bowls or something similar but i can see them splashing the water out of that in a hurry and would need to be filled everyday if not multiple times a day. Ive come across fairly big watering cups that i could add into my pvc waterer i have for the chickens. Not sure if they would freeze or not though. Or if it would be big enough for them or if they would still need a bucket of some sort to put their heads in? Anyone has any ideas that are fairly inexpensive?
