Quote: Last year we had temps up to -30. I had hay bales around the perimeter of the hoop coop last year & just put some extra hay down when we had our blizzards when the temps were so low. They did just fine. This year I don't have the hay bales. The billboard tarp I used to cover the cattle panels this year keep more of the wind out. I actually had to open up some of the plastic because the temps were in the 50s & it seemed warm in the coop.
Anyways I am all for more ventilation is good. I have 2 roof vents and the window to the door is open year round. It faces north & most winds here come from the south/southwest. My hens have never had a problem from frostbite or the cold. I don't feed or water them inside the coop. They have to come outside for both. They also don't spend the day in the coop. They go to an old covered run for the day or out in the veggie garden to dig it up.
This is the coop about 6 weeks ago when we had over 7 ft of snow. You can see the snow is piled up over halfway up the rear cattle panel.
I dont have a pic of the cattle panel on this computer but if you click on my profile pic it should take you to my pictures I have one of my coop there.
