Chickens will eat just about anything we eat. I haven't tossed table scraps in the garbage for a long time now. Natural composters. Sometimes I buy things especially for them. $0.82 for a small package of collard greens doesn't faze me. They love a treat of warm rice, cream of wheat, pasta or oatmeal on a chilly morning.
In today's treat pan for the chickens were the greens and and apple. Red and green. How fitting. It sends them into a feeding frenzy and is cures any boredom they may be experiencing. I keep a couple old baking pans on the counter and fill them up during the day with trimmings from veggies and fruits and old bread. It makes for happy chickens and healthy eggs.
Here is a list of treats for chickens...
Cereal (low sugar)
Cream of Wheat
