Okay this is the second year of winter dealing with water. I came up with the idea last year to get some insulating material, wrap it around the waterer and tape it shut so the chickens couldn't pull it apart. It worked for the most part. It kept things pretty thawed out. The thing is I bought another waterer since the other startes to rust and now I don't have that same set up and while I could copy it again I got to wondering is there not a insulated sleeve for waterers out there? I mean, look at how much other stuff has been invented for us small chicken coop owners. I would have figured that would have been made but obviously not by searches on the internet. So I thought maybe a de-icer or heater but I don't want to use electricity out there. I was hoping there was something I could heat up and then stick in the water that would help it stay thawed for awhile. I would still have to bring the waterer inside like I did last year cause something like that wouldn't keep it unfrozen for that long or with these temps. so I guess it wouldn't be worth it cause usually during the day it will unthaw on its own. Sorry for going on and on and on but all these thoughts are swirling in my head and I'm trying to find a fast easy solution like NOW so... Anyhow, thanks and any advice or suggestions would be appreciated. Oh and I have this problem with the duck swimming water so for those who own both, suggestions welcome there too.
