This weekend, we went out and bought this feeder . We needed an upgrade since the girls have been growing fast and eating their feed up a lot faster. But when i got it home i realized it doesn't have a lid of any sort on the top. We don't have a place to hang it (yet), so we were just going to set it on some blocks, so that it would be at back height. My concern is that they're going to fly up there and poop in the supply. And with our humidity, it just seems like it would be better if it were covered. Is there some reason it should NOT be covered? The upgraded waterer we got is sealed up like fort knox, so i just wondered what the difference is. Why no lid?
