I need as much info as I can get.
I have an insulated coop. All walls, floor and ceiling. Its 8x8. I blocked off the west facing top vents for winter. Will leave the east vent open. I have to block the vent on the north side also because too much draft blows in.
I have 11 hens and one rooster. All duel purpose breeds.
My question is, how cold is too cold?
Sometimes here the temp can drop to -40 or colder.
What temperature outside should I turn a heat lamp on? if at all?
Also my coop floor is sand for easy cleaning. Should I use pine shavings or straw over the winter instead?
I don't plan on using light in my coop to continue egg laying. I will give them a rest over winter.
I just really need some advise so my chickens are happy all winter.
Temp outside this morning was -1
Temp inside my coop was +8
