Greetings Erfan, Ray is right on....Try this for me and as Ray said, keep trying.....Green Leafy Veggies: Kale, no lettuce, mustard greens, corn on the cobb, (once a week) spinach, dandelion greens, collard greens. Carrots, cauliflower with peanut butter (just a dab), snap peas, a good quality seed with no sunflowers such as Top's or Volkman's (on Amazon), raw spaghetti. some cooked pasta, The whole trick is to give them two or three things for six to seven days, they won't starve. Leave the seeds 24/7.....Don't let the fresh food sit in cage more than 2-3 hours. You can try a spoonful of plain low-fat yogurt or cottage cheese daily I promise they won't starve.. Again, this can take days or months You are doing great!
