Thanks Rhasputin, I only offer produce once a week and usually greens, carrots or apple. Freeze dried chicken is a wonderful idea! I just picked some up, and it's cut into nice small servings, my breeders loved it. For the most part, prefer to keep my rats on primarily a vegetarian diet simply because I don't trust a lot of the animal products in feeds. But thank you for the recommendation, I will definitely make it part of my feeding schedule.
If I didn't have such an irrational hate for crickets, it could be fun to offer some up.
That's an interesting concept and sounds effective. I think if I switch to 6F or a lower protein percentage I will try something similar to make sure the breeders are getting the amounts they need. How is the smell with Mazuri 6F? Another thought I had was that higher protein = stinkier rats. Since switching to Harlan the smell has greatly reduced!
