I have 6 hens who are all around 9 months old. 3 R.I. Reds, and 3 Buff Brahmas. This is their first winter and i want to make sure i am prepared. The coop I have built is 4'x4', has two vents on the side and rear, and a north-facing glass window. The run is 12'x4', and is pretty well protected from wind by an outbuilding standing beside the coop. It seems that I have heard that both of my breeds are tolerant of cold weather, but I would like to know if i should install any heat source inside the coop itself. The last thing I want is for my girls to freeze their tail feathers off. Also, as the days grow shorter, i get fewer eggs. I was thinking about installing a LED light set on a timer. Would that help to increase egg production? And lastly, does anyone know of a DIY or inexpensive way to make a warmer for the waterer so it doesn't freeze in winter? Any advise or suggestion would be appreciated!
