Thank you!
The smaller one hangs.. I don’t think it ever went swinging

... and the bigger ones have string tied but I set them on blocks as I thought they would be too heavy to hang... but the string helps with keeping them from perching on top... and as you can see.. on the big feeder I have placed a small lightweight board on top to also deter them from hopping on the edge or going in.... a friend of mine lost a rooster that way... he went in head first and couldn’t get out!
And, is the container she knocks over made of plastic? I have one that is plastic but usually has plenty of water in it to be knocked over.. I also have string on that one... the metal containers are pretty heavy and I usually keep them filled so I guess that helps with knocking them over
