I've been feeding them ZuPreem Smart Selects which I found at Petco and has bits of dried fruit in it since I haven't been able to get them to eat fresh fruits :/ so I've been giving them that in a bowl which I think is about 3 tbs and I try to keep it filled to the top because it's pretty deep. So far I've offered them chopped up carrots, cucumber, strawberries, apple, blueberries, and apples.
I'm saving up some money for a bigger cage, but I'm not sure how big my current one is, I think the bottom is about 15 in x 15 in which I now know is not big enough ( I read it should be about 30 in) and about 17 in high. I do want to get one that will have enough room for both of them to live in with room to fly around. But I do have an office room I can let them out in and completely bird- proof since there's only 1 lamp that I can move out and my mom doesn't leave her laptop charger or anything in there.
