I have nine chickens and I have a nice coop with a feeder elevated just high enough for the chickens to reach with craned necks, and it is full all the time. However, when ever I go outside past their pen, they always swarm towards me hoping for a treat, but I really don't understand why. They have plenty of feed in the house, and it cost money to throw more into the pen. Any ideas on tastey chicken treats around my house in gardens and things. And whether I should throw feed into the pen when the come. Thanks!
