i haven't had coffee yet so please ignore typos lol
there's a lot of info about to be hurled at you
I'll start with answering your questions.
1 foraging. Easter eggs are great, and if you put live meal worms in there, and NOT close the egg all the way, leave a little gap so they can get their nails in there they will learn to get them open. Sometimes you can close them a little cockeyed so its not closed at all on one side... once they figure out and smell the meal worms are in there they will open it then you can start closing the egg normally but leaving a little gap before it snaps together.
2 toys. if your coconut hut has rope and a ladder/bridge remove the rope it hangs from and the bridge. Replace the hanging rope with fleece and they don't need a bridge they climb and jump just fine and don't need them. The bridge is made from a wood that CAN but not always cause skin irritation.
other toys, reset toys pom pom pits, pulley toys, plastic bracelets, ping pong balls, feathers (no feathers found outside or from pet birds)
3 cleaning. The more you clean, the more they are going to mark the cage and stink it up again. However, with 6 in one cage depending on the size you may need to clean more often. Usually most people clean cages once a week, clean drop trays more often as needed. I don't clean cages even that often but do clean drop trays as needed. Its up to you and what works best for you and your gliders.
4 urine odor. Yes, partially from the boys being intact and probably from their diet. And it's normal for them to pee down the bars.
5 Food/Diet.
" have a bag of sugar glider food that my friend gave me but they don't like it and wont eat it. Do I need to get calcium powerder? What is HPW and is it needed? I give them honey as a treat, does it need to be 100% organic? What are good meats to feed them? They like tuna and Vienna sausages(She has fed them these for three years)
I feed them superworms and freezedried meal worms that I get from my local petstore."
Personally I'd trow out the bag of sugar glider food and get them on a widely used balanced diet. I will address this in a minute.
* Calcium powder and do you need it. Yes they need calcium in their diet, which is why they need to be on a balanced widely used diet, the diets we use have calcium in them or the recipe. We DON'T just sprinkle calcium on food to much can be just as bad as not enough. In the diets we use, it is a measured amount, distributed evenly through the entire batch of food.
So you may or may not need calcium powder depending on what diet you choose. Some diets have calcium already in them. And some diets are recipes that you have to add the ingredients yourself.
HPW is one of the widely used diets. Hpw diets can be confusing because there are so many of them and multiple formulas for it. The Exotic Nutrition brand sucks. Personally I recommend the Critter Love Brand Hpw's

So with Critter Love hpw, you make the staple and freeze it, and you make one of the salads to feed with it and freeze it.
Another diet to consider is Bml.

This one, you do need calcium powder.
Both are good diets.
I'd stop giving Tuna and sausages. Tuna is known to have high levels of mercury and sausages are super high in salt and fat.
I'm going to hit two birds with one stone here and suggest other proteins and a TEMPORARY diet plan for you to use until you decide on a normal diet for them. This is NOT a long term diet menu but can be fed until you get them on a more nutritionally balanced diet.
Proteins. Boiled or baked chicken, boiled or baked turkey, boiled or scrambled eggs, yogurt.
**chicken and turkey can be, legs,wings,necks,breast, even ground.... what ever you have or want to get, bones are fine.
**yogurt, no non fat, no artificial sweeteners
** when cooking for gliders do not use butter, oil,or any seasonings.
Fruits. Apple, blueberries, cherries pitted, melons, grapes
veg. frozen or fresh Peas, carrots, corn, green beans, mixed veg no onions. NO CANNED FRUIT,VEG OR MEAT
Ok menu for a week........
Pick one protein, one fruit, and one veg a night, and they get one tablespoon of each category PER glider. So you will need 6 tablespoons of each on one plate, or 3 tablespoons of each on 2 plates.
a weeks menu should look like this...
MON - boiled chicken, green beans, melon
T - yogurt, peas, grapes
W - boiled eggs, corn, watermellon
T - Boiled chicken, mixed veg, cherries
F - Scrambled eggs, Corn, blueberries
S - yogurt, carrots, honeydooo
S - boiled chicken, mixed veg, cantaloupe
you can use that and rotate it as needed until you find what staple diet you want to use.
The best place to find glider vendors is on facebook.
https://www.facebook.com/groups/956786344360103/
This is group is purely for vendor posts. Anything from joeys, pouches, cage sets, toys, treats you name it.
my fav cage set vendor is Denise she makes cage sets,
bonding bags, sometimes toys....she will work with you on what pieces you want or need and you can get a whole set or individual pieces. Shes super easy to work with and her skills are amazing.

6 Bonding. your doing all the right things already. Bonding bag time and tent time are the two most used methods. no matter what you do it's going to take time, especially with a colony of 6. There are some videos on bonding as well I'll try to post some after coffee
