Every night and give them a treat in the morning everyday.
Sugar gliders should not eat chicken.
As often as you feed it to them. They don't eat yogurt in the wild.
No. In their native habitat, sugar gliders do eat small insects, but ants are not among their normal diet.
Sugar gliders should not be given yoghurt. Apart from the obvious fact that they do not eat yoghurt in the wild, yoghurt contains milk sugars which may not be suitable for sugar gliders.

It is highly recommended to get two sugar gliders. The reasoning is that sugar gliders are colony creatures, and therefore do better when they have another glider friend. In fact -- sugar gliders that are kept as singles often self mutilate, overeat (or under eat -- neither are healthy), and/or over groom. It is also very commonly observed that single sugar gliders groom less, are less active, meaner, and less healthy than sugar gliders that are kept with a companion. You should also realize that keeping two sugar gliders is no harder than keeping one... It's actually a lot more fun to have two!
