Thought We Had it all Covered... Post-Build Advice

Hi there-

My first coop lasted over 10 years and my hens lived many years even though there were many design flaws, including the only ventilation was cracks in doors or windows at the same level as the roost. So I read and "learned" about my mistakes.

We recently built a new coop, and I thought we had everything covered. Winter is now in full swing here in Chicago suburbs, and I am realizing some insulation/ventilation issues. There are likely other issues, too, so any thoughts you have are appreciated. That said, my primary concern right now is making it through the winter. These pictures show the layout in various stages of construction. At this point, the metal roofing covers the whole run, and the interior walls have been insulated.

In terms of insulation, I did not think of the doors, which are on both ends and are just plywood. No insulation there. :-/ In addition, I thought I thought about the roof, but no, not really. There's just plywood and roofing felt that goes up to about 5-6" to from each end, and then the metal roofing. The ventilation is meant to be from the open spaces in the roof between the 'bumps' in the metal, if that makes sense. I'm not sure if this picture shows it well:

I've been told if I add insulation to the ceiling, it will retain moisture. And if I do that, won't it cover the ventilation? I've read all about heat/don't heat, which seems to be a frustrating 50/50 split in the community overall. I was going to try going without, but don't feel I have the insulation/ventilation figured out.

This community has always come through for my questions, and I appreciate you all so much. I welcome any thoughts or suggestions as to what to do at this point. Thank you!

hmmm. I've been at this for most of my adult life (I'm 78) but in the south. Mostly Florida and Alabama--so hardly your kind of weather--but I did spend one winter in Colorado at 9,000 ft and have happy memories of my Pekins skiing on the ice on our pond! :D

So, with that in mind: I do not insulate. I do use 3/4" plywood and/or T111. The roof is shingles over felt and OSB. I take great care to cure any leaks or drafts everywhere inside. My windows and other vents are well above the height of my roosting chickens. I do keep a Little Giant waterer in the coop and it does not freeze even when the temps outside are in the teens (but I've never experienced temps inside the coop much below freezing. In Colorado the flock was in the barn and between the body heat of horses, chickens, and ducks water didn't freeze in there either.) I have never used lights or heat.

Even in the coldest weather my chickens all seem to prefer to be outside during the day. The only exception is for cold rain--they stay in for that.

My chickens are a hardy lot. Rhode Island Reds. The flock was started by my grandfather in the 1940s and I continued that bloodline until the 90s when some SOB stole the whole lot. It took me awhile to get over the loss. I started up again about 8-10 years later with Buff Rocks. Coyotes killed that flock. I finally tried again in 2008 with Meyers' Reds, to which I added Cackles' Reds. Now I'm back to breeding my own. So far so good.

However, I remain convinced that the key is keeping breeds MEANT for the area where you are and understanding their true needs. There are so many gorgeous breeds now but--and this is just my own opinion here--far too many of them are really NOT adapted to where or how we are trying to keep them!

Hope there is something in here that is helpful!

:D

For what it's worth, we're in central IL (so slightly milder winters but only just) and have never bothered with insulation and never lost a bird to the weather. Our first coop did have an air pockets between the outer wall and inner walls, but no additional insulation. Chickens have their own insulation (feathers) that's perfectly adequate as long as they have a dry place sheltered from the wind.

Look up woods style coops. They're almost completely open on one side. But these were historically used in the northeast and up into Ontario for commercial poultry operations. Areas that typically have much harsher winters than northern Illinois. We used a woods style coop during the polar vortex and had no problems with our standard sized poultry.
 
So you guys are saying I'm ok? The coop is fine the way it is? I have a thermometer in there and even with the insulation I already added, the temperature in the coop is mostly whatever the temperature is outside.

I am concerned about the deep polar vortex-like weather mentioned in the comments. I'm afraid that, along with a couple of days of continuous 30mph winds, will just be too cold. (Note: I did put boards up to block the wind on the two windward sides of the run space under the coop.)
 
Hahaha! I love it. Maybe I'll try down jackets with my ladies!
I think the insulation I used is called rockwool. It's covered so they can't get at it. 🙂

As it should be, means you have good ventilation.

Here's some tips about extreme weather that I've used:

Electrolytes help as much in extreme cold as they do in extreme heat.
