Oh, they will be mad. Chickens hate change. But I also hate wasting feed... and I have next to no waste now because I expect them to eat what's on the floor first.They are up at the crack of dawn and making a huge fuss. I will start your way today and see if that works. Boy will they be pissed....when they are out and my patio door opens, the entire flock comes a flapping and running...quite entertaining.
