If the value is in being able to see the birds through the wire why bother to paint the inside? I assume the visibility improvement is due to covering the light reflection on the wire?Definitely worth it! Painting it black allows better visibility of your birds. It makes an amazing difference and it's not that difficult to do. Use a roller. Paint both sides. Do this before putting it up. We're in the process of building a new run and we're definitely painting it.
