Hello Thanks for taking time to look at this post any advice or suggestions will be appreciated!!! We live in N Alabama, for the most part we have mild winters, however the temps do drop below freezing often enough I am worried about the gals water freezing. Some friends of ours gave us a submersible water de-icer from Farm Innovators model # 49N1. What are your suggestions for using it? I would like to be able to fill from the top without having to pull the lid or flip the thing over (the less freezing cold water I spill on my feet...the better!!!!) I had thought of putting a shielded heat lamp pointed at the plastic waterer inside the coop, but the risk of fire scares me. our current waterer (in the run) our current waterer (in the coop) I found this waterer on BYC's site https://www.backyardchickens.com/web/viewblog.php?id=61-4_dollar_chicken_feeder_water There is electricity run to the coop. We have installed a light and timer to lengthen their daylight hours. Here is a pic of the coop I am using all of this in.... Again, thanks in advance for your input!
