I don't think the PVC tube with a wye or buckets with ells type feeders would work so well for Blooie, not with ~20 birds. Even if you put 3 ells in each bucket you would need 3 or 4 of them so that would get expensive. And if you need to extend the fitting on the outside an inch as shown, guess what, they don't sell PVC pipe by the inch so you'll be cutting a lot of 3" pieces off a longer piece. Not too bad if you have a power miter saw, heck of a lot of back and forth with a hacksaw while holding the pipe down (easier if you have a vice on a bench). 9 to 12 street ells, a length of pipe plus 3-4 buckets (I would probably choose square, easier to cut the hole). But I don't think I would want the birds having to shove their whole heads down to the shoulders in a hole to eat.
I think Bee has the right idea - some sort of lean-to roof over a multi bird feeder. You can get a 10' plastic gutter for ~$7 and another ~$7 for 2 end caps. Or you can make one of Leslie's horizontal PVC pipe feeders (with carrying handle
). It would be stiffer but more expensive ~$20 for the pipe and ~$8 per end cap. Hers are held up off the ground in cement blocks stood on end with the pipe in the upper holes. And of course, since my mind is running with this: you could make a roof for this simply by putting a ~2' wide piece of plywood or metal roof on top of the cement block! Easy
I suppose you could get fancy with this and instead of cutting the pipe ALMOST in half (so you have the handle) horizontally, you could drill holes about 30 degrees from the top on each side. If you have 1 hole every foot, you can feed 20 birds all at once. Not sure what the diameter should be for the holes but you would need larger holes in the top at some undetermined spacing to fill the feeder because it won't flow by itself. Or a funnel with a BIG lower diameter to fill through the feed holes. Or a screw auger to move the feed along. I'll have to stick this in the back of my head for the future (probably not the screw auger part though
).
