Thanks for all the input. keljonma, i do actually lock them at night. i just had them flipped over for the pics.
SSO202 - i see your picture, and think that could be done. The trim would look the best. Or, i do have some large metal things, like a big staple with pointy ends. Sorry, i don't know what they're called.
On the plexi-glass, i know Home Depot and Lowes sells the wavy panels. However, i couldn't find just flat panels. i thought i saw them once at a home depot in a lighting section, like the plastic that fits inside florescent ceiling light frames (does that make sense?). But they weren't very large. Any leads on good places to get something like 4' x 6' or 6' x 6' flat panels?
and, i hear you ChanceRider, it is nasty windy today and cold! i have this coop and run, plus two other coops and pens to get winterized. Just moved from SoCal, so this weather is a shock to my older birds.
