Week 1 a success!

Hello, I'm a newbie, I work as a Vet assistant/pet groomer for my father who is a Veterinarian (and miraculously supports my decision to feed raw) my 4# chihuahua and 11# pomeranian just started eating raw a week ago today. They are doing great, no digestive upsets and they are eating it like champs. Zoey my chihuahua has a lot of health issues, and had knee surgery on the 2nd of July so I was worried about the transition for her, but she's doing remarkable. She is allergic to chicken, beef, corn, wheat in kibble form, but so far her red skin appears to be clearing up, and she definitely isn't as itchy, and another cool thing is she no longer shivers n shakes all the time like she used too when fed kibble. Right now they are eating Chicken/Cornish Hens. I had a couple of questions, I know hearts/gizzards are considered meat, but would they be okay to start adding now or do I need to wait for another week or two? Both Zoey and Georgie have normal poops. I am planning on switching my 70# golden retriever to raw but not until I can buy another deep freezer as the one we have is too small for both hubby and I's meats and the furkids meats when I'd be feeding Shellie 1 & 1/2# per day, lol, for now she is on a rotation diet of TOTW, Wellness Core, Blue Wilderness. Anyways just wanted to share that I've had a successful week with my 2 little ones, and ask the question about the hearts/gizzards. I know that organs should come in about a month after feeding, correct?
