Clear Corrugated sheets or coroline???

I think if the local cat decides to sit on the roof at night the chooks would be better off not seeing it.

It's for the walkin run.. It's 19ft by 13ft n 6 feet high.

Would the chooks be ok in the summer as the wind can come from all sides.

Thanks joyfull.. Im thinking of corrugated all over. I'v seen some 9ft by 2.5 feet for £16.00 and they are 1.1mm thick, not sure if thats thick enough it'll have support underneath though.

I had black bituminous corrugated stuff on the roof (Wickes)  For winter I got some green tarps with eyelets from the Army Stores and lashed these neatly and securely to the back and one side, leaving one side open for fresh air.  I covered the front in winter with transparent tarp with eyelets which I got off the internet (it's for covering market stalls) Heavy duty stuff which is not cheap but the hens loved having a window on the world and being free from wind, rain and snow.  They also had a straw bale house to go in and under should they feel the need. Access to outside too of course 

Good luck 

thanks for ur reply joyfull. which would you recommend correx or polycarbonate. correx is cheaper than polycorbonate. what's the difference between these 2 lol

We have finally got round to starting the roof on our walk in run.  We have gone for some black coroline sheets with some clear ones to let in some light.  The weather slowed things down so hubby managed to get 2 sheets on and will be finishing it this weekend. 

The coroline sheets were from B & Q and if you buy 5 or more you get 20% discount.  We bought the fixing nails off ebay as they were cheaper in larger quantities.  I think Screwfix does a good deal on the fixings as well.
