Sorry to take so long getting back to you- I just weighed the girls, and the one weighs 84 g and the other weighs 116 g, not 300.
We feed them a variety of fruits and vegetables, 1 tbsp per night; they get OHPW (Candy's modified version with calcium) 3 tbsp per night.
There are 2 feeding stations, and the only bickering I've ever seen is one night I gave them egg instead of diet, and one of them was sitting on the side of the cage with a handful of egg, and the other one came up and took it out of her hand. No squabbling though- Cheyenne just went and got more egg.
We offer foraging cups both in the cage and in playroom. It varies- sometimes they get 2 different foraging cups in the bathroom, sometimes none. Sometimes I put treats all over the cage for them to find, sometimes just in one egg. We don't want them to have too many treats since that is the first thing they look for when going back to the cage.
They have a raptor wheel, which they love to run in. We want to get another, but haven't yet.
Out of cage time they get approx. an hour a night, sometimes more if they won't go back in the cage.
