Welcome to the thread!! it is 16 out this morning at 4am- I went out at 4 and got the 5gal. water jug and brought it in the house. I only filled it 1/4 of the way and added 1/4 tsp of electrolytes . I go out every 2 to 3 hours and check it.And this is our first winter with birdies![]()
the main thing list you may already know

keep them dry
no wind/breeze
no frozen water
add electrolytes "like rooster booster brand" to the water when needed
dry food [free feed- I keep feed in my feeders all the time, the chickens eat when they want]
keep the windows closed if you have them
For their own good I lock them in/keep the door shut what I know it is to cold for them to be out in it, their feet and combs will freeze.
