Help with homemade food

Hello, I have a 5 year old standard poodle, I’ve started to slowly transition her over to fresh food over the course of a year, she’s doing well, eats good, poops well and has an endless appetite but I would like to continue doing better for her. I want to make her food from scratch and just want to get an opinion on the list of ingredients I will be putting in to see if there’s anything her diet is missing. Thank you in advance.

The carbs of her food will be a mix of oats, brown rice, quinoa and barley

Her protein is an 80/10/10 mix of ground chicken bone and organs or a 60/10/30 of ground chicken + bone, organ and fruit/veg. On special occasions she’ll get a 60/10/30 of beef, beef organ and fruit/veg The fruit and veg will be a mix of apples, bananas, carrots, lettuce, squash and bell pepper

Additionally, I slow cook a pound of duck feet to use the collagen rich broth to cook her food, toss the large bones and grind the small bones and add them with whatever meat is left. This broth is flavored with the honest kitchens turkey powder broth and the goat milk powder

I don’t know if it’s necessary to add additional healthy fats but if it is I can add coconut oil and maybe some smaller fish, although I prefer to stay away from seafood because of the mercury content. Any help or criticism would be very helpful, I just want to make sure she’s getting the best. Thank you!
