Check these out and let me know what you think. I recently lost 20-25 quail because my pens weren't as secure as I thought they were. So I built these. The taller one is for my chukars. The smaller for my cots. I installed two layers of hardware cloth about 3 1/2 inches apart. Installed heavier hasps with locks. the lumber is 1 1/4 rough saw poplar. I'm concerned about the light and vent screens on the front of the small pen. Is the single layer 1/4 x 1/4 hardware cloth sturdy enough to keep out a raccoon? Have I missed anything else? I really don't want to lose my new batch.
