One of my 6 week old pullets, an EE, has a bad habit. She stands at the hanging feeder and continously whips her head back and forth through the feed slinging it out of the feeder. Then she stands and scratches, repeat etc.... I haven't noticed this behavior in the other 11 pullets. I recognize that most of the spilled feed will eventually be consumed but this is definitely creating some waste. Other than culling the EE (it crossed my mind I will admit haha) any suggestions on changing this behavior?
