I have a wonderful, inexpensive source for layer mash. Unfortunately when I feed it the girls make a huge mess by flinging it all over the place. Seems like more goes on the ground around the feeder than into the chicken. Does anyone have any ideas on how to stop the ladies from making such a mess with mash. I switched back over to pellets because I couldn't take it anymore and I was worried the feed on the ground would attract rats. I use both an open feeder and one of those hanging types.
