I've seen some PVC pipe feeders for chickens and other smaller poultry and was wondering if it would work for emus. Right now my sheep try to bully my emus away from their food, so I have to shut them in the barn for an hour or two so the emus can eat in peace. I'm afraid my emus may not be getting enough to eat throughout the day since there's not much to graze for in the winter around here. I tried using tubs and pails with holes cut in them that were big enough for the emu heads but not for sheep heads (my sheep have horns that can get stuck too if the hole is too big and they're persisitent). But the emus couldn't see the food well and just couldn't seem to figure out that was where they were supposed to eat from, even when I dropped in grapes and other favorites. I love 'em but they just don't seem the cleverest. My parrot could probably open a combination lock if he wanted the treat badly enough Any suggestions appreciated.
