This is quite a hard thing to accomplish. Chickens eat more if they eat with the flock. They've done some research on it. I guess it's a family meal type thing. You might achieve similar results with adjusting the treats you give her. You know I'm a meat and fish fan for chickens.I'm trying to think of how to get Peggy into a routine of eating alone. Of the four chooks, she's the one who's fanatic about eating with the others. Her obsession is so blinding she doesn't even see her own special food bowl. This is how I came to give them all enzymes. I have to try harder to establish a habit of Peggy eating alone.

This is what I do here if I'm trying to get more food down one and they are not contained.
