Thank you, Kab
If you are talking about the bigger chick, that is an Autralorp ... I have 3 that are 2 weeks old ... and I think what you called a BO is a Light Brahma ... the BO is the darker gold colored chic...

I think the soft netting should be fine.. Only thing i have to say.... Is you better get a hard roof with good supports before about october... Knowing how the snow falls here where we live lol I highly suggest clear vinal roofing...

They used the roofing... It helps keep heat out in summer, But in winter the suns rays, Help warm it like a green house affect...
I will hard roof it either this fall or next spring ....

That's the first thing I thought of, too, - snow in winter will collapse the soft netting.
I hope you're building good roof supports, Tony, so you can install those corrugated panels real fast come December.
I have corrugated fiberglass panels on my run. I have intense solar radiation at this altitude (7500') and the clear ones let in so much sunlight in summer, the pen cooks. As I added on to the run, I found the white, opaque panels were the best color, letting in maximum light in winter while providing some shade in summer. They hold up very well under snow load, too, but I rake the snow off with one of those roof rakes.
Thanks for the info, az ...for the roof supports I was going to do 2x6s every 2 feet .. sound ok?
here is the run ...nothing left but the roof/netting ... tomorrow I cut the door in the coop and release the hounds!!
