Yep, this.
It's not a bad idea to switch around a little bc of the chances of allergies (and just for nutritional variety too) - but it's not absolutely necessary either. I think what's definitely important is that you save a few novel proteins, in case of allergies developing.
I feed mostly duck (premade raw), but I do switch it up every once in a while both for nutritional variety and to avoid intolerance developing. Plus, I think it's nice to not eat the same exact thing all the time.
