My chickens free range in the back yard. I have 6 large oak trees in my yard that are dropping acorns like crazy. When I go to feed my chickens they follow me like puppies all the way to the feed can. A few days ago I noticed they had stopped following me and were pecking something. When I walked across a concrete pad, I had crushed several acorns and they were eating them up. I gathered several gallons of acorns and crushed them and the feeding frenzy was on. I will pay a minimal food bill for the next month due to the love of acorns by my chooks. I hope this saves someone else some money due to feed being so high.
