My grandpa feeder is about 3 years old, I used it with my original birds, but ended up taking it away cause I got new birds who didn't get the hang of it. Well I am trying again. I'm 2 weeks in with the beginning setting. . I see 3 of the 5 are eating out of it. My chickens hate eating out of anything except the ground. Will they get the hang of it? Will see next week when it goes down a setting.
