Diets for my squirrels

[NutmegAndGinger]

My best guess is that my boys are about 3 and a half months old. This is a list of how and what I am feeding them, and if anyone has questions/comments please feel free to share! I want to provide them the best diet I can so any input is welcome!

Upon waking they both get 2 HHBS (for young squirrels)
An hour after they get some formula
Before we leave the house they get a hand full of vegetables.
As soon as I get home I give them 1 more HHB each.
About an hour after that they get more vegetables.
Before bed they get some more formula.

Veges they are given thus far (I only started them on veges a week ago so we're still testing out what they like and dislike):

Escarole - leafy.
Cauliflower
Broccoli
Brussel sprouts
Portobello mushrooms.

They have never had fruit or nuts yet, any suggestions on what is healthiest for them that i should give first?

They are not huge fans of the mushrooms but I'm am going to push them because I've read that mushrooms are a good source of vitamin d. I'm going shopping tomorrow and would like to pick them up some more veges, so are there any recommendations?

For my house guests I haven't had a squirrel yet turn away from Snap Peas or Radicchio.
The best recommendation would be to follow what's on the healthy diet list, it offers a pretty
good assortment to choose from.

I plan on trying all of those vegetables, however, I feel like they would get bored solely with those choices. I will try your suggestions as well. Thank you!
