Treats are not necessary, but I would suggest a few raisins out of your hand if you are looking to spend some time with your birds, or hold an apple out for them, and let them peck on it. A normal diet for my layers in the summer months is about 20% scratch grains, 10% black oil sunflower seeds, and 70% starter pellets. I also provide oyster shells separate, and give them greens as much as possible. If you can't get greens in the winter, you can use alfalfa pellets. In the winter, I drop my starter down, and add in some whole corn. I also only feed them a certain amount, I don't leave a dish of food for them, I feed on the ground and make them scratch for it. By controlling their intake, I have very healthy birds with this diet. If you leave a dish of feed out for them all the time, you will need to adjust for this. Hope this helps a little.
