I feed mine lots of things. I cook scrambled eggs for them every Saturday. I add calcium, cheese, yogurt (each has vitamins and calcium and protein) Want to keep my babies healthy. I save all of my egg shells and clean them and put them in the oven for 15 minutes and I let them cool and then use my food processor to grind them up. This is Calcium for them and I add it to whatever I give them to eat. I cook them pasta, elbow macaroni noodles, grapes, spinach, tomatoes, pumpkins. They really love bread and they almost tackle me if they see I have it when I come outside.
Pumpkins are supposed to be a natural dewormer (actually the seeds are). I take the seeds and grind them up and add buttermilk or regular milk and yogurt and my calcium. It is like a smoothie and they love it. I got this idea from Penny from BacktoBasicliving.com.
and they love lots of different fruits and veggies as well. My husband says they eat better than the dogs do, but they are loved so very very much.
Oh and I purchased 5000 mealworms over the summer and wanted to start my own colony so I could feed them to my chickens. I have got lots of mealworms and 1 huge tub and then large tub with them in there. It is now time to start to give them to my girls. they are gonna love them I am sure.
