Waxworms. I also give a tiny amount once or twice a week of black oil sunflower seed to my flyers. Stoneyfield Whole Milk French vanilla every night. Mushrooms every night (mine like the ****ake ones the best). I mix up the veggies and fruits every night. They only get either an almond or half a pecan 3 days a week. Mazuri rodent block every night (mine do eat it most of the time). I have cuttlebones and deer antlers in every cage. One of mine does have seizures, hers are stress related. Flyers are high stress animals, and have seen quite a few that have seizures. I also do give hhb's to them a couple times a week too, but break the blocks in half. Luna is 10 yo, Eris is 7, Rocket is 8 and Cashew is 9.
