covering the run with plastic to keep snow out is 4 mil ok to use

I have not used 4 mil. My coop has weather walls made of 6 mil plastic. The sun is the big problem here. It killed my expensive tarps in 6 months.

 

I used a heavier plastic, to keep rain out. Not sure about the 4 mil...that seems awfully thin. Wind will tear thin plastic to pieces in no time.

 

4 mil. might last a month or 2. Generally, 6 mil. that isn't UV protected is good for a season. Since it's just walls, it might be worth a shot. If the wind doesn't get it, the sun will. I've read that you can paint it with white exterior paint to extend its life if you use it for a hoop house. That may help it get through the winter.

 

We used a heavy tarp. Left open on the bottom and rig front so we culd get it. I will try and post a photo.

 

This is my 1st winter, but I enclosed all sides of my run with clear shower curtains. They were attached with furring strips & screws. I sure hope it works. I like the clear, so I can see the girls from my house and they can see what's happening. I did leave the south side open where the people door is.

i do love the fact its like clear, so your flock can see out. mine is boring blue. not exciting, and we too have the door opening clear of tarp, the chickens are gather up over there, so they can peek outside.

 

We wrapped our run last weekend w/ 6mm plastic from Lowes. We just did the north & west sides & under the coop part. It held up to the wild winds we had last night, 35-50 mph! Be sure to use some strapping too as I don't think just staples will hold it all winter.

 

4 Mil would probably make it through the winter if it is secured properly. Keep in mind though that you will be creating a giant kite for the wind to blow over. You need a very sturdy built and anchored run to keep it in one place. What is going to keep your run from collapsing with the weight of the snow on the plastic?
