WINTER COOP Minnesota

[johny]

Hey, any of you Minnesota chicken keepers.
I want to know what you do and how effective it is for wintering your birds.

I live just north of International Falls, Minnesota.
A month of nights going down to –35C (-30F) is normal for January. Occasionally we get –40.

My coop is an 8x8 shed.
The ceiling is 6 ft. 4in. high.
I insulated the walls and floor 2 inch Certifoam. The coop sits slightly off ground on blocks. I figure winter snow will quickly block and insulate any chilling effects of wind going under the coop.
The ceiling has 4 inches of Certifoam.

There is a single pane slider window on the south. That will be closed for the winter.
The north wall has a 2 foot wide screened opening for spring, summer and fall ventilation. It will be sealed with plywood and 2 inch Certifoam for the winter. I plan to put a 6 inch dryer vent through that for winter ventilation. If we get a nasty Arctic blow, I will seal the vent until it is over.

Inside will be a 100W light bulb 16 hours per day. I have a 125 Watt water dish heater.

Planning on having seven Buff Orpingtons living through the winter in this coop.

Will this be enough insulation?
How about winter ventilation?
I still have a hard time reconciling insulating vs. wasting heat by ventilating to prevent humidity and ammonia build up.

I forgot to say... we lined the whole coop with straw bales on the outside. I know you were thinking the snow would insulate, but the straw does a better job until the snow accumulates. Ours is up on bridge planks in case I ever wanted to move it, so there is a little air space under mine too.
We don't have any mouse problems with the straw. I took them away as soon as it melted.

I live in Mahtowa, MN and this will be our first winter with a dozen Cochins. After all the reading I've done, we plan to keep our 8 X 12 coop open all day, every day, regardless of temps...and closed at night only because of predators. We have an enclosed area with chicken wire on the top but even racoons would get to them at night if they werent closed up. Otherwise I'd leave the coop open all the time. Only way for them to become cold hardy well acclimated birds! I have horses also..and they absolutely do wonderfully being out in 50 below temps as long as they have hay and warm water. I hate to see people blanketing them and messing up what mother nature gave them.....which is a brilliant natural system to stay warm in the coldest bitter temps. Here is a good article on cold care... blog.mypetchicken.com/2012/11/16/cold-weather-chickens-8-things-not-to-do/ We MAY end up using a 250 watt red bulb at night..... will have to just see how it goes. As of now, no intention of heating it.

Keep them dry and out of the wind....too much chicken breath will give you too much condensation in there and result in frostbite.

Also, a 100w bulb wouldn't do much other than provide light.

I have two 250w heat lamps plugged into thermocubes in my coop and my coop is 16 x 8, fully insulated. It doesn't get quite -30 here but it's gotten close with the windchill. I did lock all of my birds in for about a week last winter and managed to keep it from getting too terribly freezing in the coop. I think the low was 16 degrees in the coop and that was after a day-long power outage and -20 with howling wind.

Using pop bottle waterers helped a lot, too because a warm bowl of water in the coop will add to the moisture in the air and promote frostbite.

Also, that probably won't be enough ventilation...I have two large vents that I can close and two windows that open along with a design/layout that allows me to leave the door open but not let the chickens out...I only shut the west vent ONCE last winter and that was because the snow/freezing wind was coming in sideways onto my bantams.

I would have thought the soda bottle waterers would freeze. How did you keep them from freezing?​

The inside of my coop stayed above freezing for the most part but I changed them out twice a day...

I'm located about 40 miles north of Fargo/Moorhead and get a lot of the same kind of temps, although you guys are always a little colder!

I used one of those flat panel heaters and mounted it lower on the wall in the coop. I loved it and really needed it! It got cold! I bought mine for around 35-40 dollars at Fleet Farm in the heaters section.
I also use a thermometer that tells temp and humidity. One of those that has the antennae in the coop and the display thing right here on my desk so I can see how cold or hot it is as I'm in the house. On the worst cold snaps, I also hung a heat lamp with a 250 watt red heat lamp. This year, we added on to our coop, so I'll be buying another flat panel heater and ditching the heat lamp. I just read so much about fires and even though I made sure it was secured by more than just the clamp, I was worried about it the whole time.

I think you will be needing a heater too! These seem to be the safest as far as fire hazard.

It got too cold to let them out in Dec and Jan. so I shut the pop doors and put a bale of straw in front of them to cut down on drafts. I also covered the windows with plastic. I plan on doing both of this things again this year. Everything went well, no lost toes, combs or wattles to frost bite! The average temp in my coop in December and Jan (with the heater and heat lamp going,) was 5 below-10 above. My coop is insulated with R-13 insulation walls, roof and floor. No north windows.

I'm so hoping this winter will be milder! We're due for one!!

We're in a snow zone too-

ND Sue.

Was your -5 to+10 temperature range in Farenheit or Celcius?
Zero Farenheit seems like a really cold average temp. Don't the eggs freeze quickly?
