I have a flock of 75 chickens... ( It's my first time... My husband wanted 400 so I'm lucky I could talk him into only 75) I go out and check to see what they have eaten every night... For the past couple of weeks.... I have noticed that all they have eaten was the Shelled Corn in the feed leaving most of the meal behind... Has anyone else had this problem and if so how did you fix it.
