Also you will find cheap and easy solution where you loosen the bottom screws that hold the screen down. Then use a flat screw driver to "pry up" this flange. Put some pennies or other coins under the flange. Voila the water drains out. The coins do not rust. Not elegant but it works. No one but you and me will know. Try it. It cost 2 cents times a few places.

I recently did something very similar using flat aluminum strips cut 2 1/4 inches long. As noted above you loosen the bottom strips, insert the new strips and retighten the screws. I did about 3/4 of our birdcage and it is working great in that area, I missed one corner and we currently have a puddle there, and i will be doing this area shortly. NOTE I previously had some drains installed, which kinda worked, but the doors started to fail and we had anoles getting in. I have sealed these closed now.
