Mine love parsley about 2 times a week. What about pepper especially red (not hot of course) it is rich with vitamin c. I give them a slice of orange about 2 times a week. Baby spinach. Also you can try brocoli, mine dont care for it. I read someone here that they gave yams. I tried it last night and I guess they liked that since it was gone. I just gave them a small slice each. They love corn on the cob. I cut about an inch off and give them each that about 3 times a week, they love it.
