Was there supposed to be a picture of your new feeder you installed?that quickly though?
Up until recently we fed them a whole mix of things thinking mixing our own feed would be cheaper it wasn't.
Our last batch of feed we fed them was 2 50 lb bags cracked corn, 2 50 lbs layer feed (crumble), 1 bag scratch grains
As I took advice from other posters we have now switched to 4 50 lbs bags of all flock (pellets) with 1 bag of scratch grains
This is our new feeder I just made and installed today
